gas checks in 357 mag

[dakotasin]

fellas... i want to work up some nuclear-level loads in my 357 mag using cast bullets, but i can't find any commercially available cast bullets for a 357 that comes w/ gas checks.

does this mean i need to keep looking, or does this mean gas checks aren't necessary?

Cast Performance gas checked bullets can be bought from Midway or directly from http://castperformance.com

i was hoping to stick w/ 158 grain bullets - or something close to that; cp has gas checks for 180's and heavier...

so, is there a source for ~158 grain cast gas checks, or are they just not necessary?

I haven't seen commercially cast .357 gascheck bullets in a long time . . . and that was just from a local guy at a local gun show. IMHO the added cost (materials and labor) involved in making cast gaschecked bullets probably dictate a noticeably higher price, which greatly reduces the market, unless you're aiming at a niche like CPB which specializes in heavyweight LBT designs.

I found I had to cast my own - the Lyman 358156 is a good design, with two crimp grooves.

If you go to the CP website, they list a 160gr .358 gas check bullet in their product catalog. Midway only sell 180gr and up.
