I am shooting Lapua .308 brass and it has been a few years since I was really into shooting this .308. I started reloading for it again and want to utilize some Winchester brass mainly due to cost. I don't recall how to measure this bushing. The current one that I have is marked 335. I do know that I have tried this size before on Winchester brass and it did not provide enough of a crimp on the bullet so I need a size smaller? Thanks for the help.

So when you refer to "mic" can you use a caliper, or does it have to be a micrometer.

Measure the outside diameter of a loaded round. You then subtract .001"-.002" for your bushing size. I used the Redding recommendation of -.001". Some say for autoloaders, you should go -.003".
I use .331" for Winchester brass, .333" for hornady, .337" for Federal , Speer and Military brass. I used a digital caliper to measure and it worked fine.
