I have three .500s: a 6 ˝” 500 PC Hunter, a 5” JRS and a 4”. The Hunter has a 2x Weaver scope in Warne QD mounts so I can swap back and forth easily. The JRS and 4” both weigh about 57 oz. and are intended for carry in serious woods. I like the JRS the best. It doesn’t have a comp and rolls more in the hand. The comp guns roll less, but recoil straight back. I prefer a little roll.
I hand load for this on my Dillon 550. Many of my loads are pretty mild: 325 Speer HPs in front of mild loads of Titegroup or Universal Clays. I also like 325 to 375 LFP stuff. Universal is great for light loads. I have recently gotten some Longshot. It should be good for more than mild, but less than wild, loads. I like Lil’Gun for loads approaching full power loads. The nice thing about the .500 S&W is you can load it down to achieve loads equivalent to the .500 Linebaugh.
The only one of the three I have attempted to test is the PC Hunter. It seems to be able to easily shoot into 2” at 50 yds. With as much recoil as this thing has, it can be a bear to shoot from the bench.
