GunTuff Pellet Sizer .177 & .22 [4.50 4.51 4.52 4.53 5.50 5.51 5.52 5.53]

Product Information

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. 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 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 After washing your airgun pellets as described above you should lubricate them to stop them oxidising (unless you plan to use them immediately). Oxidation on the surface of the pellets will increase the friction between the pellet and the rifling in the bore, so the passage of the pellet down the bore ‘judders’. You don’t want that to happen. Mitch, I think that pellet sizer that Ted used was a custom made job from a personal friend of his? This simple shade can be snapped onto the Chrony and gives an effective shade for the light sensors.I have one of these somewhere and I didn't see any difference in accuracy when I was doing alot of pellet testing

The more you use the sizer then the more skilled you will become in using and feeling what is correct. Each pellet and calibre of pellet will have an average weight measured in grains. The idea is to weigh each pellet and reject those that are “outliers” and fall outside the limits of the mean weight. If say a .177 pellet weighs 8.6-gr, a plus or minus weight of 0.2-gr will not make much difference to velocity or accuracy. You are looking to reject the 0.5-gr-plus oddities. Some words from the product’s first user: “ A great product. Very light. The UK Neil sizer slides into the ink well holder for a perfectly snug fit. Enables speedy sizing and any pellets dropped fall onto the top of the well. This stops the odd dropped pellet falling into your sized pellets by mistake. Perfect.“ It's been a while since I've looked into pellet sizing properly but when I have in the past it seemed 50/50 whether it made a difference and I've struggled to find anyone able to actually quantify the difference & remove placebo from the equation.

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. 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

You don't want "a" sizer as you don't know which size your gun likes the pellets sized to, so get a set, something like these: https://www.jsramsbottom.com/guntuf...4-50-4-51-4-52-4-53-5-50-5-51-5-52-5-53-.html 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. PointedIn the 1990s the company was bought by Sheffield-based Walden Engineering to become Walden Sizer Ltd. Since then the company has thrived in Sheffield, with support from firstly OSL Group Ltd and now the Newburgh Group. Use the same method as for washing the airgun pellets but this time add a small amount of lubricant. There are many pellet lubricants on the market. I use two types: Napier and Daystate. The Napier comes as a liquid and a spray while the Daystate is spray only. Two drops of lubricant is all you need but because a .177 has a different surface area from a .20, .22 or .25 pellet you will need to experiment a bit to get it right. 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. 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.
