[QUOTE="bruce_ventura, post: 858709, member: 34084"] Recoil only part of the problem. Shock and vibration also increases with bullet energy. The Zeiss should be fine for at least 500 rounds. I recommend using quality mounts, and lapping the rings if they are not fully machined. 1,400 yds may be close to the theoretical maximum for that caliber and scope, but it may difficult to actually get that in practice. It will help if you are at a high elevation. The problem is that the barrel can be installed crooked by 10 MOA or more, and barrel vibration can throw off your zero by 5 MOA or more from boresight. I see both routinely on production rifles. You could find your self short of adjustment at either 100 yds or 1,400 yds. In that case you could use Burris Signature rings to dial in the boresight alignment of the scope. [/QUOTE]
