The days of a 2.800" short action magazine are about over, hornady them selves are trying to change that when the 6 .5 prc came out. I thought of getting a 6.5cm even passed on a good deal on a kimber, or like to have a rifle to shoot factory ammo for back up but haven't decided it's worth it to buy a 6.5cm.
I like the 260 tho I'm not a huge fan, I'd rather a swede, 6.5x57 or the 6.5 rem mag,prc. But I get a little ticked when the cm guys crap on the 260, it was designed at its time for what shooters wanted and used. Hornady got it into the heads that 140s were the best and all the other unicorn tales they were claming. It took years for the 6.5cm to catch on, then shooters discovered what many already knew the 6mm are better.
