I load my 357 Max carbine with Lil Gun but have other powders; 296, H110, 2400 and more but with my 18" barrel Lil Gun gets the speed and accuracy nod with 158 to 180 grain bullets. In our limited cartridge zone in Michigan it works very well and we have taken many deer with my 357 Max carbine.
I would think the modern 350 Legend carbine is a very close relative if anything nothing more than the 357 max without a rimed case. you could look at loading data for that cartridge if you are using it in a carbine.
Handguns are another story and there are a few here that are real good with reloading for them.
