I have one of the first new .44 Special Flattops.
It is the only .44 Special I own and the only one I've ever had the slightest interest in.
I didn't buy it strictly because it's a .44 Special, for me it's a combination of elements that united for a specific purpose.
The size and the ballistics it's CAPABLE of are near ideal as a relatively compact big-bore reliable single-action handgun for use on the two-seater ATV in large animal backcountry territory.
I have .44 Magnums, one or two of which do travel on occasion (including a .44 Mag Flattop), and I'm not overly sensitive to recoil. But, I've never personally bought into the "buy a caliber & then download it" idea. Others like building plinking loads for their .30-06, shooting .38 plinking loads through their .357 Mags & .44 Specials through their .44 Mags, but I don't.
I buy a particular gun for what it was meant to do with its full-power caliber, and if I want to plink I do it with a "plinking-calibered" gun.
Just me.
The .44 Special is "special" to me only in this gun.
I have a full-sized Blackhawk in .45 Colt that'd be the primary outdoor carry gun, IF the smaller .44 Flattop had not come along.
Both have the same 4 5/8-inch barrels, but the .44 just feels trimmer.
The barrel length on both allows the gun to travel in a holster that rides high enough on the belt for instant access if needed. Longer barrels don't ride as well.
All of which, to make a short story long, leads up to me carrying the .44 Special flattop with a handload using a 250-grain lead Keith semi-wad with a charge of 2400 chronographing at 1060 FPS.
In discussions with Taffin, he's found the gun will handle even more velocity with the same bullet & powder, but this load gave me good accuracy in working up to it, better ballistics than most standard factory .45 Colt loads, and a shade less recoil than a fullbore .44 Mag.
You know when it lights up, but it's not unpleasant to shoot, and the energy figures should be sufficient for its intended use.
The gun's been lightly altered with a red front sight blade insert & white outline rear blade, and a Belt Mtn base pin.
Purpose-driven, accurate & reasonably powerful.
The overall package is why I bought that .44 Special.
Otherwise, no interest in the caliber at all.
But- it certainly CAN be used with something other than 1910 loads.
