I'm doing research for a varmint rig (heavy benchrest). Probably 20br. How does the Berger perform and at what velocities? I've read some reports of the 55gr Berger penciling through PDs. Also I've read some about 20-250s and 20x47 Lapuas not killing coyotes cleanly at short range (<200-300 yards) due to the bullet breaking apart to early. Regardless of cartride, what are your experiences with the Berger varmint bullets? Particularly the 20cal 55gr. The Berger bc is so much better than a 40gr vmax, which would be my next choice.
