I have a Ruger Redhawk 44mag. Bore slugs at .431" and throats at .432- .433".
Bought a .430" Lyman lube die with it. I had not even heared about slugging the gun, as this was around the time I got into casting.
Bore leads and so-so accuracy at 25y, with .430" quenched ww. Borrowed a .431" die from a friend, and got some improvement. But still not good enough.
I am considering lapping my .430" die to .432-.433. My only concern is lube leak between the die body and the stem. This will be the first time I am trying lapping.
Do you think it would be a problem?
Mold is NOE 429421 dropping at .434
