I find 75 yards an amazing distance for a pistol. Judging from my spreads so far (hand rested, I am still getting into the BP grove) I would be lucky to hit an elephant at that distance.
I have my pistol Eyepal mounted to my old glasses now (see the fix, which is an electrical crimp terminal cut to fit!). The nose pieces are glued on, after 30 years or so I guessed it was time to replace them!)
As for preferences, I am both a rifle and pistol guy. I focused on pistols as that was my after work entertainment on a 6 x 10 work week (wilds of AK you could go shooting in any gravel/borrow pit). Rifles were for hunting, so sight in at 100 yards and off we went.
That said, my take is whatever floats your boat on the cartridge conversions. For me the BP aspect is what is interesting. I have other modern cartridge pistols to shoot. The BP is more fun stuff for me. I got to shoot an AK semi auto. It brought a serious appreciation to what that gun was about and the BP pistols is the same.
