Kinda cool. I'd rather have one in 45 Colt so there would be room for powder and a heavier flatface bullet though.
I shoulda had them thread my BHA 500 S&W levergun....
A few years back I wanted to get my short barreled 444 working at sub sonic with a 300 grain bullet . Bear in mind this was a 1:36 twist barrel and I had no luck getting accuracy with the speed I wanted . If I’d gotten it to work I was going to thread the barrel . I do believe it might very well work with a newer Ballard rifled 1:20 barrel , but I don’t have one of those I wanna chop and or thread .
