the 92 winchester is a small 86 and not weak at all, many have be converted to 357-44 magnum. the 44-40 had a hi-speed factory load that shot a 200gr bullet at 1800 fps, but was dropped because the winchester 73 and colt single actions would not take the pressure, but the 92 could as has two sliding bolts to lock the action. a 92,s action in good condition will handle 40,000 with out a wimper. i don,t plan to load any of my 92,s to that high a pressure as there is no reason for me to, as i count on shot placement to kill quickly. rossi made their 92 clone in .454 casull that is loaded close to 50,000 C.U.P. and i don,t think the metal in 92 rossi,s is any better than winchester 92 metal even with the age difference. eastbank
