I'm going to buy a AR-10 type rifle, probably never shoot it but what's one more in the safe, seams like a reasonable investment. Like the .243 version but the twist rate may be a bit to slow for my taste. How are your experiences with the .260? I want to stick with one of the H rifles, simply for the shorter barrel, and the fact that it's already threaded 5/8-24 so I can run my cans on it.
