"Disenchanted" implies that at some point I was enchanted. The only round that comes close to that for me is the 45 Colt.
I think the .45 Colt is a very good round. Several years back I owned several guns in that caliber and they were from different makers and eras. From one gun to the other the bore diameter varied by as much as .007 and cylinders by close to that amount as well. I could get each gun to shoot some ammo accurately but it took time and effort reloading and shooting select commercial ammo. At the time there was too much on my plate to fool with it. So I set the 45 Colt aside. I was not disenchanted so much as too busy with other guns and ammo to give it the time it deserved.
