I have been toying with the idea of linning the barrel of a 51' colt navy for conversion to 38 special, the liner is so that I could use standard ammo and not have to use hollow base bullets to get decent acuracy.
Would this work from Brownell's, ".38-40; .40" groove diameter, .590" (15cm) O.D., 1-25 twist"? The barrel length will be 5 1/2" to 7 1/2", haven't decided which revolver to convert yet.
My main concern is the twist rate. This gun will be fed a steady diet of cast lead ammo and posibly black powder loads in the future and will be used for cowboy action shooting, along with plinking.
Thanks,
Will
