Just cast up a pile of 155 gr gas check bullets for my Rossi 92. With a single cavity mold as well.
I believe it's a 358 456 mold. Found it on eBay last year. I think it makes a great bullet.Looks like 50-50 plain base & GC. What mold? Have you been in my garage? That looks eerily similar to my bucket with a paper cutter handle sticking out...parallel universe maybe.
I like "Keith" style SWC and HP forms. I also get a "kick" out of casting and shooting the single cavity WC "ash cans". For a 38/357 Handi-rifle, a Ruger Blackhawk, and an SP101, I feed them:
ST - Steel; BR - Brass; AL - Aluminum
