I want to order some gas checks for a 162 grain SWC saeco mold bullet. I cast it with Lyman #2 lead from Rotometals.
I shoot it in my Marlin 1894 Cowboy 357 Carbine with 13.0 grains of 2400 powder with CCI 550 Primer (approx 1600 fps according to Pet Loads by Ken Waters.
My question is this----- I read that Hornady gas checks are CRIMPED on & Lymans are PRESSED on. Is this correct ? & if so , Doe's it matter.? Anyone out there in Bulletland that has experience with both types. Thanks , Saggitar
