headspace gauge clarification.....
I've seen and am hearing that on the 308Win, Forster has a set NO GO gauge length of 1.634.
Clymer and PTG have that NO GO set at 1.636.
If I have a set of Forster gauges, should I just use the 1.636 as the NO GO gauge, or remain at the original NO GO gauge length of 1.634. OR, should I just standardize the system of the NO GO being 1.636?
I know the 308 vs 7.62 NATO differences in gauge lengths, but why companies have different set standards for 308 is a little baffling to me. Looks like it should be standardized..
My question is.... which is it?
I'm setting headspace on a couple of builds, and want them to come in at 1.632/1.633.
Just want clarification as to what to look for on NO GO length and what set standard I should use. Thanks!!
