You know what my vote would be for. GRIN.

I've been toying with the idea of trying to get a 54cal bbl from Lyman for my Left handed Deerstalker. In talking to Doc White. He suggested getting a 58cal with shallow groves as there is a more selection of bullets for the 58. Don't know if I'll do either right now as funds are a little low. Plus the amount of deer I see especially on state game lands don't warrant the money I would have to spend.
