Your right I didn't say what caliber I'm using, my mistake, sorry. It's a 5.7 Johnson Spitfire, 22 Carbine, on an XP100 action with a Hart 18" barrel bedded in a Brown Bech Rest stock with a 12x Leupold AO scope. I like cast bullets and should be able to make them shoot fairly well with this rig. I have cast some bullets but don't know everything so I thought I might ask or take advantage of the knowledge on this bord. Thank You
