Re: 7mm - 162 AMAX
Doug, Any bullet will blow if the impact vel is high enough. The issue is what will be the impact vel, not the muzzle vel.
The amax is not a heavily constructed bullet so impact vel over 3000fps should be avoided. For LR shooting, that will not be an issue as after 300yds, the bullets have slowed down enough to work well.
If you anticipate some close shots, try the new 162gr SST. That should handle the higher impact vels and still expand downrange.
