Howdy guy's,Had a member here P.M. me.He was asking if it was alright to shoot Hornady Light Magnums in a Reminton 7600.I think 100 grainers.Said they were recomended for "Fixed Breach firearms Only".I did not want to give him bad info or cause a problem with the rifle not knowing howhot they load the light mags.I would think they would still keep the cup down enough for just about anything 'cept maybe an old custom rig made out of a not so strong military action.Thanks for the help and let's get this guy on the right track.........................Alton
