Some interesting results of ammo fired from snub revolvers at this year’s revolver round up by the guys at Active Response. . Almost none of them expanded so the general conclusion is just carry a round that gives adequate penetration and minimize recoil from +P and other JHP ammo in a snub. The one exception I saw was the Gold Dot Short Barrel .357 load. This happens to be the round I carry in my S&W 340 M&P snub. The same round in .38 special was pretty disappointing with no expansion. Seems like a wadcutter or semi wadcutter would do just as well in .38 special. Also some interesting results in 22 LR. Some would say it has no use as a self defense round.
