I have a 6.5 GAP 4S Titanium action Mountain Rifle (6lbs. 10 oz. W/O scope) built by Jim See from Elite Accuracy. It pushes the 156 Berger at 2850 fps (sea level) and in 2019 I stoned two bull elk with this rifle, distances weren't far (150 and 250 yards). I was shooting Copper Creek handloads, 24" barrel, box says they should be going 2930-50 fps, barrel isn't fully broken in.
