Alright, so I've admitted before that I'm a cast-boolit fraudster in that I do not cast my own. My apartment balcony is not big enough to host a pot, and the first batch of powder coated boolits would be the last thing I ever put in that oven. To that end, there's a few companies that take pity on the cast-impaired among us and offer pre-cast and pre-coated boolits. I'm considering just buying and loading one single projectile to various speeds for .357 to (hopefully) serve all my .357 guns, at least until I can finally afford the cabin in the woods.
The guns in question are a .357 Mag Contender (factory bull barrel, 10" and now threaded), a 5" New Model Blackhawk, 4" GP100, 3" GP100, and 3" Smith&Wesson Model 60. Are all Magnum chambered and aside from the threading on the Contender all are factory and in very good condition. If I were going to load up one Boolit to serve in all of them, what would it be?
I'm thinking something between 158gr and probably south of 180gr, .358 diameter, and certainly polymer coated. I'd like to be able to run subsonic in the Contender using a 9mm suppressor (Osprey or Striker II) at low muzzle pressures if possible.
158gr RNFP? SWC? 180gr HP?
Is this pure folly, or am I a genius? I realize that I'll likely not see ideal accuracy with all of them, but so far all seem to shoot well with Magtech 158gr SWC and Winchester 129gr .38SPL.
