I've had both , a 10" octagon 3030 , and at present a 357 Max in 10 inch bull. The 3030 was pretty intimidating , a lot of muzzle lift and flash , and with a 10" inch barrel it doesn't get the velocity needed for a lot of " 3030 bullets " . It never shot real well for me either, I finally got rid of it.....that was back in the late eighties. This summer I got a 10 " bull in 357 max, it is nice to shoot. The recoil is not bad , I shoot 180 gr XTPs over 296 , pushing about 1800 or a little over....they're a little hot. As someone else said, you can use 357 Mag or 38 through it also for practice. To answer your question....I'd go Max all the way. good luck
