6.5 staball and the 6arc

[Mel]

well 6.5 staball works in the arc with 90g bullets
used it to fireform some 7.62x39 brass today and accuracy with the un fireformed brass and staball was suprising stopped at 30 rds to snap this pic

now that the cases are fireformed i need to shoot a ladder with them and get some chrono data , 6.5 staball and the 90g fmj might make a nice very soft shooting close to midrange sd load

I ran a couple of ladders with StaBall, accuracy was fairly good. The problem was velocity, top performer in my CMMG barrel was 31 grains under 103 grain eld-x at 2540 FPS. The 103 got 2472 FPS with the same charge out of my monster barrel and 2431 FPS with the 90 gr eld-x on top of 30.3 grains of StaBall. YMMV of course, still have the chrono data if you need anything from it, let me know.

Barrel length for these velocities?

Both barrels are 20”
