My Klein's ,Chicago, late '50s Martini Cadet rebore to 357mag
has 12 twist rifling.  Shoots the Lyman 358315 200gr RN over a caseful of 4227 very well. This bullet has a long nose and short body and so does not take up too much space in the case. I have other longer heavier 38 cal bullets I could 
try, but It is very pleasant to shoot with the 200 gr bullet. 
Also, I thought about rechambering to the 357 Max, but "why bother"

I have a Ballard 25-20SS with a relatively new 10 twist barrel. A breech seated 121gr Borton spitzer shoots bugholes with AA #9 powder. SD's are low single digit. What a fun and pleasant gun to shoot. Wish all mine were this accurate and easy to load for.

I rebarreled my early 32 JM Ballard to 25/20 SS. The extracter fits as is and there won’t be any pressure issues.
