Product Information

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. 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 Our pellet sizer has an adjustable stop that goes through the centre of thesizerbody, the sizer has a tapered bore. To use the sizer just drop a pellet into the larger hole at the bottom and push the pellet (with the pusher supplied) until it reaches the stop. By unscrewing the adjuster it will make the pellets smaller, while screwing it in will make the pellets larger,this is when the pellet is pushed to the stop with the brass pusher. From my experience shooting air rifles there area few kinds of pellet that stand above the rest in terms of performance, power and quality of manufacture. Bear in mind that pellets will behave differently in different rifles, even those of the same brand and model. So this is just a guide to what works well in my experience, and for the people I have shot alongside. Recommended: Air Arms Field My sizers have a stainless steel ejector plate as well as the screws that are either side of the main adjuter. There is also an option of have a 4mm Stainless Steel Ejector plate under the options tab.

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. 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 This is just a guess, but it’s going to be a pretty educated guess based on many years of testing and reviewing airguns. While valving and barrels certainly play a major role in the overall accuracy of an airgun, if the ammo isn’t consistent, you will always be shooting at a moving target. 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? 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.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. 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 most popular pellet gauge tool is probably found at www.pelletgage.com and they are still making gauges that can identify pellet head size in a lot of different calibers. Once you’ve identified the exact size, you can then start to look at variances in weight.Let’s talk about that next. 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.

The shape of the pellet is almost as important as the size, and there are lots of different styles of pellet available that all perform vary different roles. Choosing the correct style of pellet can effect drastically improve the effectiveness of your shooting. Flathead or Wadcutter A varied selection of pellets, in different sizes Where 1” at 50 yards used to be “great,” it’s now seen as the baseline for performance on any PCP. Expensive PCPs are expected to shoot MOA or SUBMOA even to begin to get taken seriously. This has put pressure on the ammo industry to rise to the occasion and make better, more consistent ammo. Not All Ammo is Created EqualThe 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. The late Don Nygord, world champion air pistol shooter in the 1980s, once wrote that he could not see any difference between sized and unsized pellets. Don sold target airguns and pellets to shooters for many years and perhaps had the opportunity to test this theory more than many people in his quest for perfection. 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
