45/70 choke
« on: August 22, 2006, 10:53:35 AM »
My rifle seems to have a choked bore.........  the groove diameter is .457 at the chamber and .455 at the muzzle. I have tried .457  .458  .459 .460 diameter bullets and I get leading with all . Should i be using .455  >   I have also tried .456 .  All of the bullets above were tried with pure lead to additional varying degrees of hardness  using wheel weights mxed with lead.   Thanks

I doubt if the choke is causing your problem. What are you using for loads? Also, you might do better with a lead/tin alloy like 20 : 1. I'd try that sized .458 with 13gr of Unique for starters. Sometimes a lack of tin seems to promote leading.
