38/9mm bullet designs that are good in both.

[awaveritt]

What would be good compromises for bullet designs that would work in both a 38 revolver and 9mm pistol? If the barrels slugged close, I might could even size 'em the same. Anyone else done this?

I would say a .356 in 9mm may work in both if the .38 is tight

You could get a .358 mold and size it down to .355 or .356 for 9mm. Undersized lead bullets generally yield poor results. A round nose design would probably be the best as far as functioning in both (especially the 9mm).
