I am considering using an existing 0.308 rifle barrel with a 1:10 twist for a 32 S&W Long or 32 Long Colt.
This will be a stub on an H&R action.
I believe the 32 LC had a 1:18.75 twist and the 32 S&W had a 1:16. I see a Douglas barrel in 1:14 mentioned on the CVA site.
My limited knowledge says if you want to shoot a heavier bullet, you spin it faster. But what about spinning it up too much, is there such a thing in the Pistol caliber speed zone?
Speeds will fit inside 600-1000fps, likely in the 7-800 range, but who knows?
This caliber normally is 75-100gr area but I may venture outside those numbers just for the knowledge gained.
Please chime in with your thoughts, even it is to say stop right there.
