What kinda accuracy you getting with the 64 gr. BSB?. IME, not that easy getting them to shoot good groups, including .223, .22-204 and .22-250 fast twist.

I've had much better results with the Fed Fusion 62 gr. That one is easy. Here's a link to some info on that bullet. Both bullets have good terminal performance.
