I am planning to have a couple of barrels chambered for rounds that have 40* shoulders, one is a 22-250AI and the other is a custom dimensioned 7mm short mag.
I am just wondering if there is any downside to the 40* shoulder. On the plus side it is giving me more case capacity, and brass that will not grow very quickly. But is there any trade off or things to beware of with a shoulder this steep?
BTW, this is in a precision rifle where cases will have the necks turned, be fireformed, and then only be neck sized inbetween firings. No full length sizing is likely to occur...at least I can't forsee a reason for it.
Would I ever have to bump the shoulder back??
(I'm still new to reloading)
