The only problem you'll have is whether the hammer is strong enough to punch through the harder SR surface.

Trial with 5.5gr TrailBoss in a .357/158gr LSWC went out at 914fps w/ a normal CCI-500 SP, and actually went *down* in velocity (880fps) w/ the CCI-BR4 SR primer.

The SP, however took two strikes to ignite shot #4, and wouldn't go w/ multiple strikes w/ #5.

Accuracy was unaffected (and was unexceptional in both cases.)
