Thank you Marrakai.
I rechambered that last one I bought for 12ga which really wasn't much different from the original chambering.
This one is going to become a rifled 20ga. My last loading in my NEF had a 510gr slug on top of 100gr of 777, but I would like to see where I can go with smokeless within the limitations of the action.
With the size of the rim, I also thought about cutting an extra barrel for something using the .577 range of cases (as long as it would fit past the block.)
I read the Greener book regarding the later actions with the hardened breechblock for higher pressure calibers.
Would that be the Martini Enfield?
He mentioned that the untreated actions would be ruined if subjected to high pressure loads.
Cheers
Tom
