What are ya'll trimming your brass to? Just got some new 300 Norma Mag Brass and need to get it all prepped and loaded up... Also looks like I'm going to have to open up the action a bit to let the brass fit into the hinged floor plate bottom metal.
New brass length is 2.484" right now...
EDIT: What shell holder you using? With a little bit of research I ordered the Hornady #38 for the 416 Rigby and it's too small... Looks like I'll have to wait till next week to shoot.
