British .303

[gumpokc]

Jon, the .303 or the .308 would work well for what you want to do with it, and not alot of difference between them in performance.

the .308 may have _slightly_ better availability, but you shouldnt have to look too hard around here to find .303 ammo.

I know you were looking at 91/30's for abit, all three are roughly equal. The differences in between them show up more on paper then in normal usage.
