"Nope"Would you chamfer and smooth the case mouth of a once fired cartridge you did Not trim?
It depends.
Plinkers, no way.
Match loads, sized with a XDie, when I'm getting ready to push a $0.15 SMK down that neck, I look and chamfer if it's not already.
That would be nice - with a Lee Zip Trim and hand tools it takes quite a bit more time.At rhis point, every rifle round that I reload goes through the Giraud trimmer - they are always trimmed to the same length with the inside and outside of the case mouth chamfered. I can process at least 400 pieces of brass per hour, so there is no excuse for me to not prep the brass appropriately.
