Hodgdon's web site has a Titegroup load for 357 Magnum that is, essentially Buffalo Bore's #20A +P 38 Special 158-grain SWC "FBI Load." Hodgdon's lists its pressure at ≈ 22,000 C.U.P. Were I to use that specific Titegroup load - but loading it in 38 Special brass - I anticipate pressure would be higher. Since Hodgdon's pressure listing is low for use in 357 Magnum revolvers, would you agree the load would remain safe to use in 357 Magnum revolvers?

I have a great number of once fired 38 Special brass. My total amount of 357 Magnum ammunition/brass is five factory cartridges. The intended use of this 357 Magnum handload in 38 Special brass is in "J" frame S&Ws and Ruger SP101s in 357 Magnum. As Laurence Olivier repeated often in the thriller, "Marathon Man": Is it safe?
