While not a 500, I do have a 460 I bought new 5-6 years ago. I reload my own ammo, and not being a glutton for punishment, my loads are on the lower end of the spectrum. I preferred the 460 over the 500 due to the fact I could also reload / shoot 454 Casull, .45 LC, and even .45 Schofield in conjunction with the 460 ammo. I reload for all these calibers, so it just made sense to me. I do have 325 gr. factory HSM "bear loads " for when I ride my Polaris Ranger up into our Montana mountains { Grizz and black bear abound} . I have never had any issues of a any type with the gun, and is literally a blast to shoot. In fact I had it to the range last week, and put 200 + rounds {45 LC and 454 Casull reloads } thru it, flawlessly ! My advice if your on the fence about buying a 500 is ..if in doubt, then don't !
