Hollow Ogive Slugs It is also possible to make a hollow ogive slug which can be the same shape and length as a reglar HP slug, but considerably lighter. If you just specify a "standard" design, we will assume this means 3/4-E round nose and a hollow base. The velocity of the 15 Grain Type B Slugs was down to 402.4 feet per second, with a retained energy of 5.38 foot pounds, this figure representing a best-of-test 93% retention of the starting muzzle energy. Air rifle slugs differ from airgun pellets in a number of ways, the most obvious being their shape and weight, which influence their ballistic coefficient. So you think you have it dialed in, but what you actually did was dial in the muzzle jump. To make the mold, cut a pellet sized hole in a piece of wax-paper or aluminum foil. This is done in two steps, using a CSW-1-S or CSW-1-H core swage die first, with a large hollow point punch, then the PF-1-SP (or -HP) die to finish the ogive shape. 4. But, of course, there’s more of these being introduced every month! LW-10 lead wire (of a diameter smaller than the die bore, so it will easily fit prior to swaging). For my testing I was sent three types of slug in .177 calibre – one batch of slugs weighing 13 grains and two weighing 15 grains that were of slightly different shapes and were marked ‘A’ and ‘B’ respectively. Weight(s): 50 x 13.2 grainsAverage velocity: 537.4 feet per secondVariation: 4.9 feet per second over a five-shot stringMuzzle energy: 8.47 foot poundsBest group size at 30 yards: 8mmAverage group size at 30 yards: 13mmAverage depth of penetration into ballistic gel at 30 yards: 157mmRetained energy at 30 yards: 494.2 feet per second / 7.15 foot poundsPercentage retained energy at 30 yards: 92%, Weight(s): 29 x 15.0 grains, 21 x 15.2 grainsAverage velocity 446.8 feet per secondVariation: 5.5 feet per second over a five-shot stringMuzzle energy: 6.65 foot poundsBest group size at 30 yards: 17mmAverage group size at 30 yards: 17mmAverage depth of penetration into ballistic gel at 30 yards: 131mmRetained energy at 30 yards: 381.4 feet per second / 4.84 foot poundsPercentage retained energy at 30 yards: 85%, Weight(s): 47 x 15.0 grains, 3 x  15.2 grainsAverage velocity: 431.9 feet per secondVariation: 2.3 feet per second over a five-shot stringMuzzle energy: 6.21 foot poundsBest group size at 30 yards: 11mmAverage group size at 30 yards: 16mmAverage depth of penetration into ballistic gel at 30 yards: 158mmRetained energy at 30 yards: 402.4 feet per second / 5.38 foot poundsPercentage retained energy at 30 yards: 93%. * A general guide to the design of an air gun slug - With all slugs, diameter is very important. These pellets, often referred to as bullets or slugs, are formed in a swaging machine. AVS Airgun slugs and Pellets are handmade in the USA. Swaged pellets are nicely formed and accurate ammunition for high powered PCP air rifles and pellet guns. Another thing I really appreciated was the inclusion of a slip of paper that informs the shooter that the slugs have been pre-washed and benefit from a coating of lube. So really they’re only for use in powerful PCP air rifles. The slugs I’d be shooting were supplied by Pro Hunter Swaging, a British company that produces lead air rifle slugs in .177, .22, .25 and .30 calibres, with a choice of weights and hollow point head types within each calibre. I chose to shoot some slugs in a regular sub-12 foot pound rifle – and in .177 calibre as well. As a projectile flies through the air, it will slow down due to encountering air resistance, and while its mass remains the same its energy will deteriorate over distance. I tested four slugs for this shootout. You can either make the slugs with the PF-1-SP alone, for either the standard HP/solid ogive style, or you can first preform a cylinder with a large hollow cavity, and use that WITH the longer hollow ogive ejector punch to make the hollow ogive style slugs. The Huben K1 is delivered from the factory with the black synthetic stock. The matter of oiling an air gun is a touchy subject with tons of debate. The best five-shot group measured 17mm at 30 yards, with the average group size measuring the same. Lay it on top of one piece of (moist) clay. Those Air Venturi slugs look to me like they come from the same molds you see and read about here. With slugs, the traditional diabolo shape used to manufacture a pellet has been cast aside, with the slug more closely resembling a bullet, as this has a better ballistic coefficient, or BC. Air Rifle Slugs Australia is the only place where you can buy High Quality Air Rifle Slugs manufactured from Nielsen Specialty Ammo With-in Australia. You want a snug fit. The velocity of the 13 Grain Slugs was down to 494.2 feet per second, working out to a retained energy of 7.15 foot pounds and an impressive 92% of retained energy. The gel needs to ‘bloom’ – to uniformly absorb all the water – and once it’s set it needs to be melted down again and reset in order to attain the proper consistency. While air rifle slugs have been around for quite a few years, they seem to have enjoyed a massive boost in popularity over the past 18 months or so, possibly because there seems to be a corresponding increase in popularity in the number of air rifles operating at FAC levels. It was going to be interesting to see whether weight or shape would be the most important factor, or a combination of the two. Going electric is much faster, but will generate more bubbles. I own a Bulldog, Texan, Slayer, Cricket, Marauder, Kral or other airgun and want to know what slug shoots best out of it. Selecting the right ammo for your Air Rifle. The implication of this is that the bore diameter of a suitable air rifle for these slugs will need to be quite large to prevent potential jamming. But this improved long-range accuracy potential is not a given for any air rifle. The H&N Slug HP 23gr 0.217″, The FX Hybrid Slug 22gr 0.217″, the Neilsen Specialty Ammo 23gr 0.217″, and the brand new JSB Knock-Out 25.39gr 0.216″. GET THE RIGHT PROPORTIONS: The key to making good gel is the ratio, which is 1kg of powder to 9 litres of water. 31st Jul 2020 How to tune your 2020 Series Huben K1 Long Range Air Rifle to shoot Dale Riggert's Varmint Knocker 28.5gr .22 caliber airgun slugs and H&N 30gr .218 diameter air rifle slugs with the best possible accuracy. Check out the large selection of calibres, weights and styles. 6. This video shows how to slug your rifle barrel with lead slug or Creocoat. We offer high quality precision airgun slugs from .22 to .308 calibers. 3. Ballistic gel is a stabiliser derived from animal collagen that can easily be made at home, but needs to be stored at around five degrees centigrade for it to maintain the correct density. The pellets travelled into each block of gel by an average of 140mm before coming to a complete halt, while the 13 Grain Slugs penetrated 157mm, the 15 Grain Type A Slugs went 131mm and the 15 Grain Type B Slugs travelled 158mm. I began this phase of the test with Rangemaster Sovereign pellets, again to set a baseline, with the pellets’ velocity now reduced to 635.0 feet per second, equating to 7.70 foot pounds of retained energy, which works out as being 84% of muzzle energy. The ballistic gel can now either be shot as is, or sliced into smaller blocks with a sharp knife. Bob Strene, an occasional poster on the air gun threads of this forum, has mentioned that best accuracy for air gun slugs often come with slugs sized under bore by .001" to .003". And while it was the norm not that long ago to have an FAC rifle running anywhere from 26 to 30 foot pounds in .22, there’s now a staggering choice of power levels and calibre options, with air rifles with a muzzle energy of 80 foot pounds or even higher no longer being unusual. Having cleaned and re-leaded the bore a final time, the 15 Grain Type B Slugs were being thrown over the chrono at 431.9 feet per second, with a variation of 2.3 feet per second over a five-shot string, yielding a muzzle energy 6.21 foot pounds. 2. They point out that their slugs are hand-swaged rather than mass-produced, and are checked for quality. In .22 caliber, slug guns need to produce a Muzzle Energy of 40 Joules or higher. PCS-1 or PCS-2 core cutter (depending on the diameter of lead wire -- PCS-1 cuts up to .365, PCS-2 cuts anything). Length is more important than width, as your pellets or slugs will probably travel further through the gel than you expect! With these pellets, which according to my scales weighed 8.6 grains, the Red Wolf had a muzzle velocity of 758.8 feet per second, giving a muzzle energy 11.0 foot pounds. More retained energy is better. With slugs, the traditional diabolo shape used to manufacture a pellet has been cast aside, with the slug more closely resembling a bullet, as this has a better ballistic coefficient, or BC. You don’t need to be Walter White to cook up a batch of the brown stuff – just follow a few simple steps. Alternatively, you could coat your mould with some cooking spray. Pro-Swage Die (specify diameter, nose, and base shape -- normally a 3/4-E round nose and hollow base, but Keith noses, cup bases, and on high power PCP guns, even flat bases are popular). Skirt thickness must be proper for the air pressure at the muzzle. The average weight of the slugs in this FX Hybrid Slugs test review was 21.86 Grains. On a small-scale level, this equates to 111g of powder to 1 litre of water, so you’ll need a means to measure out both. Over my Shooting Chrony F1, they had an average muzzle velocity of 537.4 feet per second, with a variation of 4.9 feet per second over a five-shot string, and a muzzle energy 8.47 foot pounds. This is a testing medium that is designed to replicate muscle tissue, and while it’s intended for bullets, it works perfectly well for slugs and pellets too. The most common weight was 21.84 Grains, which was attained by 30% of the slugs tested. Somebody is getting a pretty good markup. While these results may look similar, the slugs all did one very important thing the pellets did not – they tumbled. The accuracy benefit of slugs is found particularly in their resistance to changing wind conditions. You might have some issues with diameter and hardness if you purchase what is in stock at the local gun store. Of the 15 Grain Type A Slugs, 29 slugs weighed 15.0 grains and 21 slugs weighed 15.2 grains, and I used the 15.0 grain ones from this sample for my further testing. The best group size at 30 yards was 11mm, while the average group measured 16mm. Said to be the favorite ammo for the Huben K1 (.22 or .25), these slugs can also be shot out of other brands of air rifles that have the power to do it. The 15 Grain Type A Slugs slowed down to 381.4 feet per second at 30 yards, energy now being 4.84 foot pounds, representing an 85% retention rate. In every case, the slugs ended up facing back to front after hitting the gel and travelling a short distance through it. “If a slug gun is fired while you’re not holding the forend down, the barrel will jump and throw the slug up in the air, as much as six inches at 100 yards. I was off to an excellent start with the 13 Grain Slugs, as all 50 weighed 13.2 grains. I used my Daystate Red Wolf for this test, equipped with an MTC King Cobra F1 scope, with the rifle being shot off Dog-Gone-Good bench bags. We can make any weight size to fit your airgun barrel. Most commercial casters pride themselves on hard cast. In the UK, the legal power limit for air rifles is less than 12 ft/lbs though you can own a higher power air rifle if it is registered on your Firearms Certificate (FAC). Before shooting any of the slugs I wanted to establish a baseline, so cleaned the bore, re-leaded the barrel and checked the muzzle velocity with Rangemaster Sovereign pellets. If you order the core swage, you need the longer hollow ogive ejector to go with it. ONE SLICE OR TWO: I was able to pop the gel straight out of the mould as the plastic was flexible, but you may want to line yours with cling film if you use a rigid mould so that you can remove your finished block more easily. Just make a 2-piece mold (using a store-bought pellet as your template), with a little hole to pour the hot lead through. The idea was to test muzzle velocity and muzzle energy, then check to see how they performed at 30 yards in terms of retained velocity and energy, and what happened when they were shot into a block of ballistic gel. Required fields are marked *. In order to find out what might happen when the slugs hit a living target, I shot them into ballistic gel. Hand Cast! After cleaning and re-leading the bore with the 15 Grain Type A Slugs, this ammo was displaying a muzzle velocity of 446.8 feet per second, with a variation of 5.5 feet per second over a five-shot string, and a muzzle energy of 6.65 foot pounds. This is a always being updated page as we collect new info about air rifles and ammo combinations. Air rifle slugs differ from airgun pellets in a number of ways, the most obvious being their shape and weight, which influence their ballistic coefficient. Save my name, email, and website in this browser for the next time I comment. Made to be a big game hunting air rifle; Capable of delivering 705 foot-pounds of energy; Shoots a 550 grain lead slug at 790 feet per second; Places 3 rounds of 350 grain lead slugs touching at 50 yards; Straight-pull bolt with 2 lb. It would be great to repeat this test with an FAC-rated rifle to see whether the percentage of retained energy varies and whether the slugs would make more than a 180 degree rotation when tumbling through the gel. Win a Fortnum & Mason hamper by taking part in our short survey. First a lead core or piece of cut lead wire is … How to shoot rats by lamplight with an air rifle. That’s relatively easy to achieve with a high muzzle velocity, but part of this test was to see whether slugs would still retain that energy when launched at a lower-than-optimum velocity. I shot several five-shot groups at 30 yards, the best group size being 8mm, with an average group size of 13mm, well below the 18mm diameter of a five pence piece. I made four blocks of ballistic gel, shooting a Rangemaster Sovereign pellet plus each of the three different types of slug into each of them. 5. More retained energy means a better flightpath and a greater potential transfer of energy into the quarry animal. Slugs made by Pro Hunter Swaging are designed for the airgun hunter, and so I wanted to shoot the slugs into the gel to determine their terminal ballistic properties – how quickly and cleanly they could kill a quarry animal. While airgun slugs are traditionally used in high-power air rifles, it was interesting to see that these slugs displayed the same properties they are known for when shot out of a rifle with a muzzle energy of less than 12 foot pounds, particularly the percentage of retained energy at range. MOULD YOUR OWN: Once the gel’s been turned back into a liquid it can be poured into a mould;  I used a couple of plastic kitchen containers. Out of the 15 Grain Type B Slugs, 47 slugs weighed 15.0 grains, while three slugs weighed 15.2 grains, and again I used the 15.0 grain ones for the upcoming shooting tests. You can stir the mixture with a hand whisk or an electric mixer. cocking effort and short, smooth travel Using cold lead, a core is placed into the die and pressed from top and bottom to form it into a pellet. Swaged, not cast. We are a custom air gun slug / pellet maker. COOLING DOWN: When the gel has been thoroughly stirred and allowed to cool, the pot can be transferred to the fridge for a couple of hours where it will solidify. (boat-tailed airgun slug) for your high powered air rifle? Optional: PUNCH-RW (weight adjusting punch, with bleed hole, to pre-form the cores if desired). Calibers:.22 Hollow Point 100ct.22 (large) 35 gr 100ct.22 (small) 35 gr 100ct.25 47 gr 100 ct But the advantages of a higher BC are more retained energy over distance and a flatter trajectory. Lead wire (LW-10) of a size to fit easily into the die, Weight Pre-adjusting punch (PRO-SWAGE only), Flat base punch (extremely high power guns), Hollow base with .030 skirt (shorter barrel high power), Hollow base with .025 skirt (medium barrel high power), Hollow base with .020 skirt (longer barrel high power), Hollow base with .015 skirt (medium or lower power short barrel), Hollow base with .012 skirt (medium or lower power long barrel). I’ve held an FAC for ten years, purely for air rifle use. Freestanding chronographs like the Chrony F1 are useful for measuring velocity, and hence retained energy, as they can be set out at distances away from the firing point, in this case 30 yards. Can you shoot heavyweight slugs in a legal-limit air rifle? The results were consistent across all four of these blocks of gel and were very enlightening. The bore was then cleaned again and re-leaded, this time with the 13 Grain Slugs, and I found the rifle began shooting consistently after using just five slugs for the leading-in process. A couple of other things emerged during some follow-up testing: the bore did not noticeably lead up any more with slugs than regular pellets, despite the surface area coming into contact with the bore being far greater. IT’S ALL IN THE MIX: It’s important to add the powder to the water a little at a time, stirring continuously as you go. Diameter must be an air-tight fit to the chamber. At least compared to a traditional diabolo airgun pellet. We break down what you need to know about oiling your air rifle, including what to use, what not to use, and how often. Oiling is essential to the longevity and performance of your air gun so it is imperative to understand the basics. I used a 1.5 litre mould for each batch of my gel, so in my case needed 167g of powder. A projectile that tumbles on impact with a quarry animal will produce a devastating wound, leading to a more instantaneous and more humane death, and although the gel doesn’t take account of bone, performance like this on a rabbit or squirrel would mean an extremely ethical dispatch. Add a few drops of cinnamon leaf oil to dissipate the bubbles. Boat tail and flat base are designed for the highest power guns. Air rifles want pretty soft alloy. Standard diameters, shapes and HP specifications. Mat Manning and Roger Lait have already reported their findings in Airgun Shooter after testing slugs in their FAC rifles, and I decided to carry out some testing of my own – but with a twist. Waisted diabolo pellets have a relatively poor BC, but they look the way they do with good reason as the diabolo is the most efficient shape for a projectile fired from a rifled barrel at legal-limit power levels. Their slugs are supplied in a little jewellery bag that has been placed inside a tin. Any clumps of gel that won’t dissolve need to be removed. CSL-2 Swage Lube (also a very good chamber/bore lube for air guns, as it is designed not to diesel at high pressure). And while the pellets entered the ballistic gel with more energy than the slugs, it was the slugs that generally travelled slightly further and did more damage. Not to tight, not to loose. … Just like my regular tests, I weighed a sample of 50 slugs from each of the three types. We offer a large selection of weights and calibers and bases. Your email address will not be published. It then needs to be returned to the fridge and left to set again – this time for a whole 12 hours – for it to properly solidify.
