I've got a 2002ish 454 super redhawk. In the past, I've rarely shot more than 1 or 2 shots (with it) at the range, due to recoil. I recently installed a Leopold Scope, and the recoil has been reduced considerably. Now I will usually shoot 3 or 4 cylinder's full when I go shooting. This revolver has a major stuck case problem...very noticeable now that I shoot multiple shots. I tap the cases out with a small brass rod and small hammer. I had a ranging bull before this super redhawk, and I never had a single case stick. When shooting handloads, I have to get down into the upper 44 mag range before the cases no longer stick (with 300 gr. gas checks,..I have to be at around 1350 fps or less to be certain I won't have stuck cases...H110 or 4100 is the powder). With decent (hornady 240s which chrono at around 1750 fps) factory ammo it is pretty rare that there will be even one case that doesn't need to get tapped out with a rod and hammer. I've polished the chambers a fair bit with mag wheel polish, but have not touched them with valve grinding compound, etc., The stuck cases will not go back into the chambers once they are pounded out,..they are too big. Also, I don't recall ever shooting 45 colt through it, although I might have. I've never sent anything to ruger and I have a ton of their revolvers,..but on the phone their guy told me that a 5 shot cylinder was not available and that I would need to send it to them and they will look at it. I REALLY don't like sending my guns to anybody, is there another solution?
