Hey gents. Just noticed Lee now has a 200 grain flat point gas check slug for .357. I've been wanting to try the heavies in my 1894 for awhile but didnt want to drop the change for a "name brand" mold that the gun might not like. My carbine has Micro Groove and likes the Lee 358-158-RF sized to .358 both with and without a gas check. Anybody try this one out yet in their Marlin or other levergun?
