I am starting a new project. I bought a 458 barrel (cheap), and want to install it on my #1 Rugger 45-70. Will chamber it for 45-70 as well as I have lots of brass.
What I want to end up with is a Single Shot suppressed quiet gun with the heaviest boolit that I can stabilize. I figure since I am using so little powder, the boolit length is not a factor.
The new barrel has a 1:14 twist, will be shooting at 1050 fps. I searched to find a link to the software that will calculate the stability factors but could not find, so will ask:
1, How much over 600 Gr can I go?
2. and does anyone have a really heavy boolit mold for the 458 dia?
(Thanks guys).
