When I built my 260 AI, I built it as a single shot,, course several of my other favorite rifles are single shots, Ruger #1s, Shiloh Sharps, Stevens 44 1/2s,
"one shot, one kill"
"one shot, one kill"
6.5 Super LRI just got a big bag of free miscellaneous once-fired brass and in that bag it had 73 .243 brass and 35 7mm STW brass (which is what I was hoping would be the majority count...But I was wrong). Anyway... Now that I have all these nice .243 brass and no spare actions to use, what would be a cool wildcat I can use the brass for? I was thinking of .260 AI... But was wondering about ballistics. How well will it push the Berger 140 Hybrids? Max effective range for whitetails? MV using Varget? ME? Good load data? Just the basic questions. Also, how is barrel life?
If the 6.5 Super LR had a 40* shoulder, I'd be all over it. But it doesn't. So, I'll probably just end up either designing my own version or just going with a .260 AI 40* shoulder. Or just trading off or selling the brass for something I can use.
More velocity from the sharper shoulder angle.Why a 40° shoulder?
260 imp 30 degree. Short action 264 cal with 3000+ in a short action cartridge. Awesome!!!
6.5 SS, 3200' with 140's in a short action, and the long bullets will fit in the magazine box............Rich
How much barrel life and what's it based on. I would be shooting it more for competition and don't want to leave a bunch of time spent making cases on the ground. What is the length? I am loading my 260 to 2.870, 2.9 touches my magazines.
