They both use std. diameter bullets, so any cartridge that pushes "that" diameter and weight of bullet would tell you how well they do on game. (example, 6.5x57R and the 260 Remington)
I know they have been around a while and there's no problems with the basic case design, so if they will meet your needs for your use, they should be good.
I really like "rimmed" cases in break open guns!!
