The load data chart demonstrates that when shooting equivalent hand-loads during the bolt gun as well as the AR, the CZ 527 commonly did better than the Sunshine Satan SD-15 with the lighter bullets, along with the SD-15 usually grouped the heavier bullets far better. Obviously, barrel twist rate and chamber throat Proportions do have an impact on accuracy.

Compressed expenses of slower-burn up-level propellants are more appropriate with loading heavier bullets. naturally, Hodgdon delivers load data For each and every bullet body weight they’ve analyzed with all appropriate propellants yielding Secure and reliable ballistic data.
very best higher general performance load continues to be with 52grs of Ramshot Hunter under the 130gr Hornady SST or even the Nosler BT. These are actually utilised on photographs out to 500yds on feral hogs and can flat knock them off their toes.
South County Thanks for the short responses. I was pondering exam barrel duration and seating but attempted to keep it way too basic.
