Have any of you had any experience loading 400 gr Swift A frames in a 45/70 Marlin.
The Swift load data certainly appears anemic as compared to Buffalo Bore cast loads and Grizzly cast loads.
Also curious in the Swift bullet is designed to open up better at 458 mag velocities?
Just curious if you might be able to get 1900 FPS with this bullet out of a 20" barrel Marlin.
