Grass Range Posted December 9, 2022 Share Posted December 9, 2022 I have read not to use .408 dia bullets for the 40-65. Handloaders manual show dia of case mouth as .406. And, the 40-70 Sharps BN case mouth as .403. I use .408 bullets in my 40-70BN with no problems and no recoil. No, I cannot remember where I read no .408 in the 40-65. Any experiences either way? Thanks for your comments. GR Quote Link to comment Share on other sites More sharing options...
