I just aquired a new model blackhawk in 357 and I have several other 357 guns and see several more in my future. I want a 180grn WFN mold to add to my arsenal. My question is do I need to go with a gas check to get top performance without alot of issues from a boolit like this being pushed in the blackhawk. I really dont want to fool with checks simply because its anothet cost incured and plus I don't have a lube sizer and pan lube only. Also accepting suggestions on molds Thanks Aaron.
