With the 303 British do you "Neck Size"? I found that worked best for my rifle than Full Length Sizing.
No, not yet. I'm still working with once fired brass from an unknown source. Once I run through that I will probably try neck sizing BUT, with the generous chambers in military rifles I'm not expecting it to show any increase in accuracy. lol
