Has anyone had any experience with gary reeders 455GNR and the 454? I'm trying to decide with cal to have my six gun chambered too. Ive owned a 454 and the recoil was pretty stout but nothing I could not handle. Reeder told me the 455GNR is the same as the 454 but much less recoil. Balisticly speaking is the 455GNR able to out do the 454?
