Re: 260 owners, what accuracy w stock RP brass?
I use R-P .260 and necked Win .243 and 7-08 brass. Mostly, all I do is ream flash holes, once the cases have been F/L sized, no other prep. I buy 100 cases per year, and shoot them up to 6 or 7 times. Typically, accuracy is even across the board, and the R-P brass has a tendency to open up primer pockets a bit eaiser
My loads run a little less than 1gr under max, emerge at about 2850fps, and I could probably get by just as nicely at a lower node.
I F/L resize each time, and necks tend to soot a bit by the time the pockets loosen, which indicates to me that the necks are hardening significantly by then.
I think that case life will depend on primer pocket expansion, which depends in turn on charge level.
I think the .260 will please you. I also think it shines with the longer barrels, mine is 28". Please note that I use a SAAMI spec chamber.
The key advantage with the longer barrel is that it allows you the possibility of reaching your velocity goal at a lower node, perhaps extending brass and throat life. The 140's really only need to go about 2650-2700fps for adequate velocity ontarget at 1Kyd.
I think that drift advantages from higher velocities are deceptive. Drift is what it is. If you can call the wind right, you can accomodate it, whatever it is. Velocity may be overrated.
