hi yall !!
i tried a 20" carbine rechambered 45colt h&r barrel and it performed well with
the 230gr xtp .75" 5-shot @100yrds ~ 2566fps
then i tried a 17" carbine barrel with 260gr rem sjhp, all groups touched in 3 different
5-shot tests @ 100yrds ~2393fps
load development and projectile selection took about 5 weeks and lots of lost sleep.
i was not after high velocities, just accuracy @100 yrds
and the load data is not from any load books, just some ballistic engineering.
from my line of work, i'm really not open to give out that data.
final results showed no signs of excessive high pressures, as a calculated guess.... maybe 57k psi
please be careful......
