Product Information

The plastic/metal tipped pellets suffer from similar problems to the pointed, in that any slight variation to the way the tip is seated can drastically effect accuracy. For this reason I would personally avoid them for anything other than close range dispatching. Hollow points are more useful for pest control, but you will still find the accuracy dropping off after around 25 metres in most guns. This is simply due to the fact that the shape of the hollowpoint affects the way the air flows around the pellet. The ‘Skirt’ The best way to determine if pellet sizing makes a difference is to conduct your own test. Clamp an accurate airgun in a vice so it cannot move. Fire all groups while it is in that position. For obvious reasons (i.e., movement), don’t use a breakbarrel gun. (No modern target airgun is a breakbarrel.) Precharged pneumatics (PCP) or gas airguns are the easiest to test because they don’t need to move much to be reloaded. Mitch, I think that pellet sizer that Ted used was a custom made job from a personal friend of his?

Now you can have it with the ComBrella shade that can hold a Combro chrony and connects with a bayonet to the barrel weight, keeping the chrony on its place, aligned with the barrel and protecting it from the sunlight. Premium brands like JSB and H&N (and others) pay great attention to how each pellet comes off the assembly line, especially with their match ammo. On the other hand, more budget-friendly brands allow for a bit more slop in their ammo. This is why, and this happens quite a bit with big-box ammo, you can have one tin that shoots pretty decently and then the next shoot terribly. Or, have wide variances within the same tin. However, the benefit of the .22 pellet is its greater mass. This transfers more energy into the target, essentially increasing the force that the target is hit by. This is important for pest control as it ensures clean one hit kills, as opposed to .177 pellets that can pass straight through the animal due to their smaller size and faster speed.These are some of the cheapest pellets that money can. But don’t let that put you off, these practice pellets are made to a great standard and feature a classic wadcutter shape to cut clean holes in a paper target, allowing you to see exactly where you have shot. For this reason I think the Bisley practice pellets make a great choice for zeroing scopes in at short range and, well, practising. If you live in a state or city where air guns are treated as firearms you may be able to take advantage of our FFL special program. New version: Similar for Steyr but longer, with three air stripper plates as well. ComBrella can’t be connected to this model. The majority of my pellets were in the 4.54 head size with 4.53 and 4.55 being on the outer fringes for a .01 mm plus or minus for the 400 count tin which I thought was pretty tight tolerence. All target airguns and most high-quality adult airguns have choked muzzles that squeeze the pellet by one-half of a thousandth of an inch at the muzzle. That automatically sizes all the pellets and negates any other sizing efforts.

You can grade the extra loose or tighter ones in batches and keep the best for the more serious shooting. The taper ensures that the front to rear ratio is always the same. This will keep the front smaller than the rear, for optimum power and accuracy. Do not push the pellet into the bore of the Sizer too hard as you may deform it, but with practice you will get to know how much pressure the pellets requireto get the maximum from them. Weight plays a similar role as calibre, with heavier pellets being more powerful but sacrificing a little accuracy thanks to having more of a looped trajectory. The pellets weight is measured in grain with 8-10gr being about average for .177 and 15-18gr being about average for .22. Pellet Shape With that one test I've found the tin of JSB Monsters have such a tight weight and head size tolerance that I don't even bother to sort anymore. I just pull the pellets from the tin as I'm shooting and visually inspect them then just push them through the 4.53 TBT sizer before each shot. I have a Gempro 250 which I weighed these head sorted pellet with. My weights ranged from 13.2 grs to 13.6 grs with the majority being 13.4 grs giving a .2 grain plus or minus tolerence which again I thought was pretty tight?A warranty is provided by each manufacturer to ensure that your product is free of defect in both materials and workmanship. These pellets are not going to be that suitable for pest control or anything at long range but for the money I think they make a welcome addition to anyone’s arsenal and save you wasting you more expensive pellets when zeroing up. Other flatheads to consider : RWS Hobby, H&N Finale Match Light , RWS R10 Match Recommended: Crosman Piranha The only downside to these pellets is they are quite pricey, costing between 10 and 13 pounds a tin, with their competitors costing up to 50% less. Also there is only one grain size available, 8.4gr in .177 and 16gr in .22. These are pretty average grain sizes for pellets of this type but it would be nice to have something to choose from, maybe something lighter for faster velocities and more accurate target shooting. Other domed pellets to consider : JSB Exact Premium , ProShot Precision , Daystate Heavyweight FT Recommended: Bisley Practice Shoot a 20-shot group of sized pellets and another 20-shot group of unsized pellets at the same distance. You really should shoot at 20 yards or more to see a significant difference, although at 10 yards you can sometimes notice a difference if the number of shots is high enough.

There are also larger calibres available, such as .25 and .303, but in my opinion these are only really worth bothering with if you’re shooting an FAC rifle that is over 12ft/lbs, as the extra mass of the pellet requires more force to push it. These larger pellets are designed for hunting at long ranges and can provide devastating power at the 20-30ft/b range.

While head size is very important, pellet weight is equally, possibly more important. Pellets are measured in grains and identified in values as small as tenths or hundredths of grains. So if we take our field target trophy pellets, they are marketed as 14.66 grain pellets. But what are the variances, if any, from pellet to pellet? There’s only one way to really find out, and that’s to get a precision jeweler’s scale and weigh your sorted pellets. Let’s Bring it Home Some shooters use a penny on their thumbs to help load solid pellets. I don’t know for certain that sizing will help, but I was told that it does by a gentleman who also shoots a Talon SS.

An alternative heavy pellet would be the Eun Jin pellet that weighs 28 grains. But I think even that is too heavy for the power of a Talon SS unless you use the optional 24-inch barrel. Then the rifle will get the heavy pellet up to speed for best accuracy. Some brands of pellets will let you choose what size of skirt the pellets have. This will be displayed as 0.01 differences in the calibre, for example .177 pellets will be marked as 4.51, 4.52, 4.53, etc. The idea behind this is the wider the skirt, the better the seal behind the pellet. This provides a greater pressure behind the pellet forcing it out at greater speed and therefore improving accuracy. Some shooters are running Predators through a sizing die to reduce their outside diameter by one-thousandth of an inch. This makes them easier to load. Keep in mind that sizing much more than one-thousandth can also render them inaccurate. I only have this secondhand and have never tried it myself. But it does make sense. If it works, this is a legitimate use of a pellet sizer. I shot these 50 yd Ten shot groups with my Thomas and sized JSB monster pellets at 4.53 head size straight from the tin without weighing as I was shooting. Had two crazy flyers out of 50 shots? I shoot a .177 Thomas FT rifle. I bought a pellet gauge and sorted a tin of 13.4 gr JSB Monsters which I shoot about 820 FPS for 20 FPE

The star shape also reduces turbulence around the nose of the pellet for better accuracy. These pellets are never going to be match target winners but when it comes to pest controlling these pellets are absolutely devastating at close to medium range, even at 12ft/lbs. Other hollow points to consider : H&N Barracuda Hunter , Bisley Pest Control We have a team of expert technicians and a complete repair shop that are able to service a large variety of brands/models of airguns. Because these pellets are some of the most popular designs available, there loads of different pellets to choose from by many different brands such as Air Arms, JSB and ProShot. Pointed If you’ve ever shot competitively or know someone that’s shot competitively, then you know that ammo selection is extremely important. Ask any .22LR benchrest shooter, and they’ll be able to tell you the exact ammo batch that performs best in their competition rifle. Do airgunners need this kind of attention to detail? You better believe it. Where Does Airgun Accuracy Come From? The undisputed kind of domed pellets, the Air Arms pellets are supposedly carefully selected to to provide excellent shot to shot consistency, and even looking at the pellets in the tin, they look very uniform and free from imperfections on the surface. They also allow you to choose skirt size between .51 and .52, which is nice, with the .52 pellets coming out on top.
