Sitting on the shelf in Kesslerings Gunshop in Burlington, WA is a NIB double cavity 452423 238 gr .45 SWC mould in the Lyman box.
This was designed by Keith to be used in the .45 Auto Rim brass in the 1917 revolvers.
I already have this mold and it is great with Schofield or standard 45 LC brass. I bought mine so shoot Keith boolits out of my 70's Series Colt's but cannot get mine to chamber. Others claim they can shoot this boolit in the their 1911's.
This mould has been discontinued by Lyman and is a real good shooter.
