Thread: 222 from 223

Originally mine didn’t chamber ether
But I found that it was because I hadn’t bumped the shoulder enough
I took the die from its normal touching the shell holder setting to 1/2 turn in so there’s a cam over on the press
Then I got a nice chambering round

I started buy trimming the 223 brass 1st then sizeing but ive actually found I had better results by removing the decaping arrangement from the die and running full length 223 brass through before trimming to length

I think that the whole cam over caper just doesn't add up. I can't see how trying to compress a hardened steel die, in a steel press with a hardened steel shell holder can do much other than put unwanted stresses on parts that don't need them. Once your brass is as far into the die as it can be pushed by the ram, it cant go any further in without compressing the die body or shell holder.

Agreed. Never understood this theory myself
