I have a 260 Rem with 27" Krieger Barrel 140 grain Berger's 3030 FPS. I bought this new in 1997 then had the action trued and barrel Installed. It still holds a 5 shot 1/2" group at 700 yards. So it's plenty accurate. I took a 290 lb hog a couple years ago at 997 yards. So it has plenty of power. I have a 300 WM, 6.5 Creedmoor, 7mag, a few different ARs 7.62 x 54R 22-250,220 Swift, 243. Every time I go shooting or hunting the 260 always goes. I take the other guns sometimes it's just that the 260 has never let me down. I've taken coyotes just under 1400 yards. I've taken deer, elk, with it as well. Good luck on your discussion. I like the 6.5x284. It's only about 50 FPS faster than my 260 rem. So what's the point if you already have the 260.
