Gonna try my hand at reloading British 303. Anyone got any advice on this particular round? My brother is giving me his enfield and a mauser 8mm only he claims that the enfield has been known to send bullets tumbling... only I know my brother and his idea of reloading is a little... shall we say sketchy. I'm the opposite. I carefully measure, use micrometers, and use due dilligence when it comes to proper reloading from a scientific perspective. I'm wondering if there are any strange things that I should know about this round.
