Does anyone know what Remington is doing with Factory loads for the 7mm RUM? I noticed that the only round showing in their catalog for the 7mmRUM is 140 gn cor lokt Ultra. When I purchased the rifle, Remington was loading 140s, 160s, and 175 gn rounds. Is their a problem with the heavier loads for the 7mm RUM? Any info would be helpful. I am not a reloader, and very dissapointed if the 140 is the only available round for such a big cartridge.....
