Thanks Mickey.That bore dia will work great with the brass
I use to make them. That size also gets it closer
to a true 4 bore size as opposed to the .935 shown in the
books for 4 bore paper shotshells. True 4 bore would be
1.05 I think, and to get it that big, the 20mm brass
wouldn't have a big enough rim.What is the weight of
the 4 bore bullet in the Imperial case?.Ed
