I've had three of them, all in 44mag. You should not shoot cast or lead bullets out of them, only jacketed. I would usually shoot about 3 boxes each time I went shooting, never had problems. When handloading, loads at normal velocities are required to work the action, most off the shelf stuff should function. Accuarcy in all three guns that I had, was great. I thought the recoil was better then shooting a wheel gun, some was taken up by the action. I have small hands and was able to shoot one handed, heck my 12 year old nephew even shot it a few times. Yes it is heavy, carrying in the field was combersome, don't bother with holster at the waist, your pants will end up around your ankles! Some of the guns even have adjustable triggers. Some guns are not for everyone, this type is expensive, if you can afford it, go for it. You should be able to resell it if you don't like it. I'd get your friend to go lower, about $650-675 unless he has extra mags or other stuff, especailly if he didn't by it brand new.
