I've gotten the tightest groups so far with this pellet out of the FX Impact M3 with the heavy .22cal slug barrel. I'll have to try them out at 50 and 100 yards when the weather warms up.

Very accurate through the FX heavy slug barrel. They like the faster twist barrel. Group size 0.183"-0.143" at 20 yards. Just a bit better than the Patriot Javelin 34gr slug 0.271"-0.151" that I built the gun for, setting #8.

They don't work very well in my Walther Reign, slower twist barrel for standard pellets 1.250"-1.750" at 20 yards didn't stabilize very well.

Packaged carefully and arrived undamaged.

1 in 4 is a flyer! I was so excited to get these and take a have a little more downrange lethality from my .22 Gamo Whisper Fusion Mach 1. They were so bad I thought my scope might be loose! Nope...and all the pellets LOOK normal and uniform. I would get 2 in a nice group, then one would go 3" high, then 2" left then back to center. No rhyme or reason to it. I switched back to Gamo Blue Bombers and started shooting 1/2" groups again. I don't know what it is, but the Gamo rifle does not like these pellets...too bad.

I hv an Airmax and wanted to shoot 33gr. Too long for mag. Will .22cal/25gr fit? 18gr are going through pest too easily

Great pellets

Size matters

By ClaudeCanadaMay 28, 2021

Heavy, should be lethal on small game.

Half the pellets have damaged skirts. This is unfortunate, because the good ones are quite accurate, but who can afford to (or wants to) throw out half the ammo?

Tried 4-different pellets in my new Hatsan 135. This one shot 3/8" and 5/8" groups at 30-feet consistently while I was still playing with the trigger adjustment. After I was happy with the sight zero and the trigger I set-up an empty tomato paste can at 25-yards (very light weight). Consistently shot through the can all the way out to about 41 yards. By the time the can took it's last hit at 41-yards there really wasn't enough can left to shoot. While sighting-in I used a couple of old 1" boards for a backstop. This pellet shot right through the paper target and the first board on the first shop. Had to get heavier boards for a backstop. Can't wait to set up targets at longer ranges.

Accurate, hard-hitting.

Consistent accuracy,hard hitting,tight groups.I love them.

By ShawnUSANovember 23, 2018

Long range for air rifles means different things to different people but, this pellet can really buck the wind for those longer shots.

By ChrisUSANovember 6, 2018

They shoot awesome pretty accurate in my qb cheif can nearly hit previous shot hole at 30-35 yd

Weight all pellets seamed identical nothing that I could tell


By RickFebruary 15, 2018

These and the 33.95 GRN. are about all I use in the Sumatra .22 cal. rifle I have. I have had very good groups out to 150 yards and the impact energy is unmatched by any other pellet I have used. I keep the speed down to 1080 for my high and 900 for my low and have found that both of these pellets will give outstanding results over and over. Both are my go to choice for pest as long as there are no range issues as these are very powerful at these energy levels(not back yard friendly).

very good in the wind, outstanding energy, stable at higher velocity and long range.

By AlanUSADecember 28, 2017

As usual JSB pellets are very well formed and the skirt gives a very good seal. Accuracy in my Umarex Gauntlet and Marauder pistol is outstanding.

Would these fit a Ruger IMPACT Max Elite?

asked Zachary from USA

Has anyone ever tried in the .22 P-rod or Marauder? Thanks!

asked Al from USA

What is the length of these? Probably to long for magazine fed rifles? Like Hatson AT44.

asked Dean from USA

Can this be shot out of a Hatsan Vortex rifle ?
