I was thinking maybe .375 as the minimum dia. for big bores - how do others feel?
Mebbe 9,3? I know several who have something in that area. Ben???
Well, the 9.3x74R is definitely a medium, but they let me shoot it in the open sight "big bore" match a couple of years ago. I would probably ask for an exemption again this year (which I suspect would be granted based on how poorly I shot it with open sights the last time).
