Not a discussion most could understand without background.

- I am a cancer chemo patient, and my bones are at extreme risk. Whatever might break or bruise for the most inane reason will never heal, so breaks are not allowed. So no 12ga, no .45, no .308, etc....
- I have a huge quantity of 38sp 125g Ranger from service days, and thought a 38/357 would be a nice plinking carbine.
- I remembered better days as a kid with a lightweight lever action.

I just thought it sounded like a fun idea. No specific reason or use case, just lots of .38sp to burn. I took the .38sp citation as good, but after the purchase was made, it was pointed out that it really wants .357, and after calling Henry CS, found that they get a LOT of calls about jams, and they are almost all due to use of .38sp lighter than 15x g.

So much for a fun idea.

But it was a fair question, so no foul.
