If you hadn't caught the recent press release, Berger recently split their product line between Hunting and Target bullets. The Target bullets had their jackets thickened, specifically to preclude this from occurring. In the future, you might try sticking to those designated for Target use if you're concerned about blow ups. There's a lot that goes into this; not just fast twists and high velocity. These factors can certainly aggravate the situation, but they're not the sole causes. Check our web site, www.bergerbullets.com
for the specifics about each of the bullets in our lines.
