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. 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. MK4 – Further improvements to resolve all issues of the original design. Re-designed internal parts, spring tension can be fine-tuned with a hex key, free travel length of the probe doubled.

I haven't done near as much testing as I would like yet but wanted to share what little testing Ive done. 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. 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 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 sizesThe 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. It's important to know that due to state and local laws, there are certain restrictions for various products. 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. So the next I decided to use the 4.53 pellet sizer and was pleasantly surprised. The 4.53 sized group was considerably better than the 4.54 unsized group

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

Lubricating air rifle pellets

The two main sizes of pellet are .177 (4.5mm) or .22 (5.5mm). The legal limit in the UK for power on air guns is 12ft/lbs for rifles and 6ft/lbs for pistols, and due to the way the law works smaller pellets have to fly faster to meet this limit. This means that .177 pellets achieve much higher velocities than .22 pellets and as such provide flatter trajectories for increased accuracy. Pellets in the .22 calibre fly with more of a looped trajectory, and so they may require slight elevation adjustments, especially at range. 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. 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.

Pellet sizing was hot in the 1970s, when pellets weren’t as uniform as they are today. I own a sizer and I’ve used it to compare the accuracy of sized pellets against unsized pellets from the same tin. I have never seen a difference in accuracy, but I have heard of one reason for sizing that might make sense for some shooters. I’ll get to it at the end of this post. Mitch, I think that pellet sizer that Ted used was a custom made job from a personal friend of his?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. 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. 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 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. 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 required you can adjust the secondary adjusters that are either side of the main adjuster. These two screws have a much shorter travel but if you do adjust them make sure they are level, then use a small drop of paint on the thead and body so that the setting does not alter. 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. 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.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. This month, we take a look a closer look at airgun pellets. If you’re pondering pellet selection, whether it’s target shooting or hunting on your airgun or air pistol, this is the post to help you choose the right buy….. The correct airgun pellet selection is essential to a good day’s shooting Pellet Size A warranty is provided by each manufacturer to ensure that your product is free of defect in both materials and workmanship. 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.
