Prefer a heavy sporter (Sendero/Varmint contour ok too) in 30-06, 280 or something else with a long action and .473 bolt face. Used or new. Also, looking for a heavy contour varmint barrel in 22br, 220 swift, 22-250, 223, 6br, 243 etc. Maybe someone has a nice custom they no longer use? This is for a proposed switch-barrel project. Thanks.
