Thank you (again!) Dean. If my figures are right, a 12 gauge measures .729", a 13 ga.--.700, and a 14 ga.--.693, so a few hundredths less than .751" could be a 13 OR 14 gauge, since the 12 ga. brass was too large (.729) What diameter is a 12b that I read about in one of the posts? Is this a possibility for this gun?
