What to do with an MM ACII
I have a nice little martini metford artillery carbine, nice except for its chamber is a trifle loose so hot or normal loads back out and jam the block, and it’s foresight blade is mostly missing. Additionally it has a rather tight bore and groups surprisingly well....
How would one go about replacing a foresight blade?
Any thoughts on the chamber, it is fine with black powder but typically gets sticky with anything over a minimum load of smokeless, commercial ppu had it home in a vice being tapped open. It is marked D.P. I am guessing on the strength of its chamber, which I’d say someone tried to polish some pitting out of.
