Saw nothing today while hunting, but I had some impressive impromptu accuracy results pictured from my TRR8 shooting Federal Premium Barnes .357 Magnum 140 Grain (1,400 FPS; 610 ft. lbs.). Optic has no magnification.
At 75 meters (82 yards) I had ca. 3.2" and 3.5" two shot groups (3rd Picture). To take the shots I rested the gun's trigger guard on the deer stand's ledge; probably could get a little tighter groupings with a shooter's sandbag designed for a hand gun rather than balancing the trigger guard on carpeted ply wood.
If you don't mind the size, the TRR8 is really a premiere woods gun for the .357 Magnum. Even with the optic, the gun's combined weight is just 40.1 ounces (627 Snub = 37.8 oz.; No optic TRR8 = 35.2 oz.). Thunder Magnum loads are easily handled, the shrouded barrel gives additional accuracy. The gun is superbly balanced and fast, although in my case that is a little compromised by the optic. A great shooter in SA or DA, the TRR8 just keeps impressing me doing everything well.
