Whether or not 44 Colt is "obscure" doesn't negate the revolver. I have two 72s, one is 44 Special and the other is 44 Colt, and I shoot them both with 44 Russian ammo. 44 Russian with 18 or a few more grains of BP (depending on bullet weight and wads, if any)is a fine shooting cartridge, recoil is like a 38, and the revolver balances MUCH better than a 38, which is too barrel heavy. They point like a Navy.
