You might be interested to know that I spoke with a tech in the lab at Western who says their Ramshot line all uses more modern deterrent chemistry than the old WC### powders that Winchester and most Hodgdon spherical propellants are canister grade versions of. As a result, he said the Ramshot powders don't need the CCI magnum primers that were reformulated for those other spherical propellants in 1989. Experiments from a number of sources seem to confirm this.
