Has anybody got sources for barrel sleeve blanks that would be suitable for this sort of project? (45-70, that is)Can anybody 'in the know' recommend a proper rate of twist for Black Powder loads for this project?
Marrakai, I intended to do the pivot first, and sort of expect it to be enough. I have plenty of old doubles for ducks, but will Bismuth expand chokes like the early steel loads were rumored to do?
Are components available for non-toxic shot loads other than steel shot?
Thanks
