You might want to consider 2 rifles both in 6.5. Either a .260 or 6.5CM for targets, high volume type shooting of all kinds and then a screamer to go along with it for your primary hunting rifle.I'm looking for a hunting rifle for deer and antelope in eastern Colorado and Wyoming as well as target out to 600-800 yards for practice.
Really wanting a 6.5x284, just haven't found what I'm wanting.

Hornady/GAP has brass as well, it's head stamped. George said due to a manufacturing problem they're behind, but they should have some available after the new year. Bertram will no doubt be of higher strength, I just wish it was more consistent.
