generally the first 50 yards..
Today shot some Barnes 70grs they stayed together, looking for a higher BC in a bullet..
How did the Barnes bullets come apart??????????????/
A Sierra 80gr HPBT has a rather heavy jacket and should take the stress.
I used an 8 twist and launched 75gr A-Max bullets at the same velocity - never dusted a single bullet. I believe that if you moly coat the bullets and then load them into the lands that you will significantly reduce jacket stress
You may want to try a few of the 90gr bullets that have emerged lately.
