14" 357 MAX Polish SS MGM 6 hole base--Set feebore to shoot 180 XTP seated on second CL.

Encore 14" 6 TCU 12" twist Full bull 6 hole base--rifle forearm(Straton) Polish SS finish

Scopes Max 2-7 Burris

6 TCU-3-12 Burris

The Encore if you go .243 and you are going Varmit rig stay with the 12" twist--not the 14" I had one shot awsome but limited bullet choice-and if you are thinking as long as 20" go 6MM AI 12" twist--That would be a 4000FPS smoke pole
