Hi everyone. I am putting a heavy barrel on my 111 .300 win mag. I am in the Marine Corps and stationed in New Jersey. I was wondering if anyone could loan me a set of headspace go/no-go guages...or tell me how to set headspace without them. This is my new project rifle! I've had it for about 5 years, and it looks sort of sad sitting next to my 10FCP-K in .308, so I decided to build it up all purty like!! Anyway, any help would be appreciated!!
