Competitive Shooting: well I have given up the idea because of infirmity. but have considered for carry my cowboy rig. It.s .45 old Vaquero Stainless. 36 loops worth of heavy .45 Colt lead plus the revolver and 6 more rounds and the substantial weigh to the belt and holster itself. Probably 12-15 lbs? If I carry a Colt pattern gun in .44.40 might save some ounces, especially in the lighter New Vaquero. Suppose I could save 2 lbs? The .45 Colt was not popular until after WWII, I hyear. In the old West 1865-1930s, they carried .44-40s and .36s and some others. So it would be going back to traditional. The .45 Colt is a big hunk...of slow lead. unless you hand load or buy loads equivalent to the Cassull's. I won't try the.45 Colt carbine 340 grain bear load in the Vaquero again, that's fer sure. The.44-40 how does it compare in ballistics, that is smokeless powder, new loads? Anyone carry the.44-40?
