All interesting and useful comments given --- thanks, Henry Folk.
As I re-read them tonight, it appears that caliber match weaves in/out of most answers. Makes a lot of sense. What caught me by surprise was JCN's noting that a rifle and a handgun can not only share the same calibers, but the same magazine. That was cool to learn.
I'd like to add my own brief thoughts. Caliber match is a primary focus for me, too. I have my Henry .22LR Small Game Carbine, and a Ruger SP101 in .357 Magnum/.38 Special. This last week, I ordered a handgun from my LGS,
which will match both of these. It's the Bond Arms Snake Slayer IV (model BASSIV), a 2-shot derringer in an over/under configuration.
This stainless steel derringer comes with a 4.25” barrel, and will be in .357 Magnum/.38 Special calibers
to match my SP101.
Since BA also makes a large variety of interchangeable barrels, which fit all their derringers, I ordered a 3.5" barrel in .22LR caliber. This will
match my Henry SGC caliber. I guess I could "stretch the match" a shade by noting that I'll have a
SA handgun to shoot when I take it out with my SGC.
Granted, it’s not the typical/traditional cowboy-action handgun, but it is very much
fun to shoot!
Two and one-half years ago I sold my first BA derringer, the smaller Snake Slayer model with a 3.5" barrel. It was also in .357 Magnum caliber. I've been wanting to replace that derringer with another, and finally was able to get this new one. Right now I'm getting a small taste of the waiting for it to get in, just like RR looking over yonder hills for the arrival of his revolver!
Anyway, appreciate your good comments...thanks again.
Have a great day!
