.30 Fx 700mm liner question.

[Cernicalo64]

What is the optimal speed for the Jsb 44,75gn pellet in a 1:37 twist liner?

865-900 FPS has always given me the most accuracy with the JSB 44.75 grain. Give it a shot (pun intended) and see how that velocity range works for your rifle.

Please keep us updated on your results.

Good luck.

+1 850-900fps, I’ve even pushed them around 925 with decent results.

I have the 1/37 twist and it hates the 45gr loves the 50gr at 873

Best groups at 50m was at 885 fps aprox. Too windy to test at 100y
