In my old Model 57 (5") with 215 cast, R-P cases and 150 primers:
9.0gn SR4756 - 980fps
18.0gn 2400 - 1360fps
Both have proven very accurate and trouble free.
The SR4756 load shoots 1" lower at 25 yards.
One unerring mark of the love of the truth is not entertaining any proposition with greater assurance than the proofs it is built upon will warrant. John Locke, 1690
