So got out to the range this past weekend and was able to test 6 different brands of pellets. I observed some outstanding, some "ok" and some just plain terrible. My takeaway at the end of the day is that just because many shooters claim outstanding accuracy with "brand X" by NO means guarantees accuracy in my rifle. My tests were shot at 25 yds, using my benchrest and rear bag setup that I use to shoot 600 yd precision rifle. 5 shot groups, and very calm wind so my data is solid.
1) Gamo Red Fire 15.4g 1.785" group
2) Crossman Copper Magnum domed 1.289" group
3) Ruger Superpoint 2.791" group
4) Gamo match Diablo flat point 1.141" group
5) Gamo Superpoint TS22 2.033" group
6) JSB exact jumbo monster 6.661"
I bought the JSB based upon the fact that they seem to work so well in rifles but they shot the worst by far in my Gamo, guess it is what it is. So the clear winner is the Gamo Flat points, followed by the Crossman domed, and a close third is the Gamo Red Fires. The only issue I observed with the Red Fires is the fact I observed projectile "tumbling" at 50 yds. Not sure why this was happening, but I plan on more testing to verify this is in fact happening.
