Good post Daryl,
yes, I should have refered to them as shotgun powders rather than pistol powders.
I've always refered to anything faster than say IMR 4227 as being a pistol powder...my bad.
Although I was being sarchastic about the goose, Thanks for pointing out the capability of the 12 bore on elephants ,I personally would have to see it to beleive it however. but then I know zero about shotgun performance and loading etc.
My main interest in shotguns lies on the platform of which they are constructed. more specifically
Double guns, their construction, and how they hold up to the higher pressure generated by rifle cartridges..
