I am looking for info on Corbon loads,what I did find was page 47 in Handloader magazine Aug98,about Buffalo Bore Ammo.They caution using their heavy 45Colt loads in Win 92 [only Ruger ,Colt Anaconda,TC pistols,Marlin and Win 94 rifles]can handle their ammo! I handload for my Win 92 in 45Colt using 18.0grs H110,mag primer,and Hornady 300hp/xtp.and have no trouble at all.I think the Corbon load only uses a 200gr bullet . Have you looked at a Trails End from Win?
