I have a rather large amount of new Canadian IVI .308 brass. I am attempting to use it in a .308 M1. I ran the brass through a RCBS Small Base Full Length sizing die. The rifle keeps ramming about 1 in 10 bullets back into the case. I tried getting a Lee Collet Die to work the case neck a bit more, then got an undersize mandrel for the Collet Die, and it is still happening.
The problem has not happened with the rifle when using once-fired LC brass processed through the same RCBS Small Base die.
Sierra does not like people using Crimp dies on cartridges loaded with their un-cannelured bullets. Has anybody used a Lee Factory Crimp Die on Sierra or Nosler 168gr bullets? What did it do to your accuracy?
