I made some 162gr Interlocks with 68gr R25 which my load data gave ~3000fps.
This was a max load in one of my resources, but 70gr was a max in another source.
When I tested these loads, I was getting 2750fps average for 3 shots.
My barrel is 26in 1:9.5 twist barrel. The velocities of these loads are pretty far off what my other loads are.
I am wondering if the neck-sizing and bullet depth are affecting the pressure/velocity. I don't remember my OAL, but I tend to set it out to magazine length.
I have been pretty disciplined about working my loads up. I am thinking of incrementing in .5 gr to 70 and see how things go.
