Hello Jay,
Ive only been shooting the 475 for a short while and havent put time in with a scope and a steady bench to see what it will really do. So everything I have done is with open sights and mostly offhanded shooting.
At the range where I shoot there is a 250 yard gong, about 12-14 inches in diameter, standing freehanded Ive put as many as 3 out of 5 shots on the gong but usually I only hit it once or twice out of 5.
Shooting 100 yards open sights I average 5 inch groups shooting off a rolled up towel to support my wrist and a rear sand bag support for a rifle to support the frame. This is awful unsteady. I feel my gun with a scope, a solid comfortable rest in the hands of a better shooter 2 inch groups wouldnt surprise me. The factory target that was shipped with this gun shows 4 shots at 25 yards is only a bullet and a half diameter wide with the 5th shot making it 2 full diameters wide. The factory is shooting 400gr XTP Hornady ammo @,I think, ~1250-1300fps. My 454 factory target is a 5 shot group that is 1.5 bullet diameters wide. Both of these guns have 6 inch barrels.
FA guns really do shoot.
Have a good one,
Scott
