I don't know what is available for factory ammo for the 357 Maximum. However as a hand loaded round, it gives up very little to the 30-30 and in some cases in more versitile. I don't know the length of your barrel but the Max is capable of 1800-1900 fps with a 180 grain bullet from the 14 inch barrel of the Contender. This rivals the 30-30 big time and it will do it with less recoil. Its a very efficient cartridge which deserves much more popularity. I shot one for years (Contender) for steel silhouettes and as a deer round. Its a good one and if you reload, its a shame to leave it idle.
