Michael Sperry Sr.458 AR Questions
I am planning to ream my 458 Win 98 Mauser to .458 AR, so I have several questions I hope can be answered here.
1. Where can I get the reamer?
2. Where can I get brass?
3. Where can I get dies, including a neck only die?
4. Is there a 375 RUM / 458 AR conversion die (After initial trim)
5. Has anyone tried fire forming a Ruger 375 case?
OK, I need some advice here

Post in the Big Bore section and Jeffe will answer all your questions.
