For OPs understanding, Marine’s FA 454 Casull is sporting a Bisley grip. That grip is undoubtedly the best for heavy recoiling wheel-guns.

Firing 45 Colt soft lead through the 454 will leave a distinguishable lead ring in the cylinder. Build up and without proper cleaning prior to shooting a JHP, JSP or harder HC 454 will damage the cylinders. The advice of interchangeable cylinder is a good one.

BTW nice looking revolver. Nothing like a Freedom Arms wheel-gun. Actually they are quite a bargain compared to paying for a Linebaugh custom revolver as they run plus or minus $5K. Bowen Classic Arms run in the same neighborhood as Linebaugh, awesome revolvers.
