I'm looking at a 243 rifle with with a 1:9 twist and 21" barrel. It's the standard 'light' barrel.
My limited (!) understanding of the various compromises involved in choosing a rifle suggest this might be on the short side?
It will be used mostly for Roe, but there will be some early range work to get the loads right.
Given the intended use (Roe) and the twist rate, what are the upper and lower bullet weights/lengths I might be restricted to?
I have read a lot of the excellent info on the forum about ballistics, and played with the spreadsheet but I am hampered my lack of technical knowledge a familiarity with velocities etc for factory ammunition. Some of it I understand and some of it I don't.
