[QUOTE="Trickymissfit, post: 701742, member: 25383"] a gauge line can be whatever the guy drawing it up sets it at. Splitting the shoulder O.D. is the way I always figure it, but you could do it with a .421" number or even a .470" number. Then you also have to take into fact that chambers will vary a few thousandths here and there. I always made my own bushings to fit individual cases and chambers, and my calculations say .4575" is the number for the bushing I.D. But a .421" bushing should work just fine. gary [/QUOTE]
