DocRock, that is great.
I have had an itch for a less common cartridge rifle in the .30 to .35 range, in either a ruger or browning high wall. This checks off some many boxes I can't even count. Thanks a lot for chiming up, and for the picture.
As to the OP, in the Henry rifle (not offered in .30-40 Krag), it would be tough to beat the .30-30. That said, there is arguably not a huge difference between a full house .357 and a .30-30 at close range. I might be tempted towards .45-70 since you already have the .357. If you are thinking about getting into reloading, .38/.357 is about the best place to start.
