[QUOTE="sp6x6, post: 513606, member: 21869"] As boomtube mentioned, for most sporters it is non issue. But I shoot with some bench guys that it would be a big issue. Just thought it is nice to be aware if you have a rifle and you think your -.005, but in reality your touching. I t is not hard to visualize or measure case with a shoulder type gauge against a brass fired in YOUR rifle. I have a hand full of the hornady brass gauges, all of mine are short at least .005. If you send in a fired brass you dont have this issue. My 257 WM has enough free bore that a 87 berger is out of the brass to touch lands. Side note I tried to make a gauge for a 338 norma, with my brass and the said tap. I used a drill press and jig to hold brass, but my tap tracked at a slight angle, tried twice. This slight angle was about .002 error on reading coal, because it was crocked. I use a Sinclair gauge and my fired brass. My accuracy load is -.005. The issue is the brass gauge is made to fit any chamber, not yours specific [/QUOTE]
