I have both in 10" tubes and like both. 357 Max. is more accurate and has a longer range but shells must be reloaded for it since Remington quit making factory stuff. Every deer I have shot with the 357 went about 60 yards on the average. Every deer I have ever shot with the 41 took no more than 5 steps.
If I had to sell one, I think I would keep the 357 Max. since it is a little more accurate and gets the job done. I do love the 41 though. Heck, I bought both you might as well too. Someone had two 41 mag barrels in the classified section last week. I would make him an offer if he still has them because they are hard to find.
