I just acquired a 44 Stevens that was originally in 32 long rf, rechambered to 32-20. The twist is 28" and it slugs .306+/-.001. I would like to shoot the Lyman 3118 in it. This rifle was made after 1901 (ejector/extractor at 6:00) and before 1917 (J. Stevens A&T barrel marking.)
It has been restored to good, tight mechanical condition, so should be able to handle any pressure proper to a model 44.
Is it possible to stabilize the 3118 bullet in this twist at acceptable pressure? What velocity would be needed, and what powders would do it?
