Ok - I did slug the bore tonight and got a .308 - so at least now i know what the bore of the gun is. Don't know why sticking the caliper down the bore didn't give me the same result last night - BUT - the slug can't be lying since it was in there.
Anyway - I'm still not sure if that makes it a sporter or a 23c or both or neither -
my newest question now is - since the bore is .308 should i get smaller bullets than the .313's I've been using (to make the barrel last longer) or should I just keep going with what I've been using. If I should be using smaller bullets - what would you recommend.
Since the 30-06 (also slugged tonight) is also a .308/.307 bore - should I just get lead .308's for the 32-20?
