Yeah, the '58's (mine anyway) have got a pretty good jump to them with the 30 grains but it's very accurate and relatively easy to control. Plenty of stopping power there to. I'd hate like hell to get shot with one of them, I know that....I like using the heavier .44-40 load in the carbine to. I didn't know if that was going to work out or not but it work's just fine. It took me years to finally decide to go ahead and try it. A good .44-40 is a hell of a stinger and the carbine is so well balanced (to me anyway) and easy to use and I am just so well pleased with it. I'm telling you. I have alway's liked the carbines, partly because they and the revolver fire inter-changeable loads and partly because of the balance and all. I have never figured up (in recent memory anyway) how many shots per pound I get. I might look later on sometime. I know the container state's how many grains there is in the container but I don't remember what it is....I have sure as hell had some good luck with Triple Seven 3fff and I am willing to swear to that. It alway's ignite's with no problem and the power is alway's there. Plenty of power. (all other things being equal of course)....
