Hi Everyone, A friend of mine got a Ruger American Predator rifle in 308 with the 18" threaded barrel that we are having some trouble trying to get it to shoot. I had actually recommended he look at that rifle based on the stellar reviews I have read on here about the same rifle in 6.5 CM with the longer barrel, so I'm feeling kinda bad. He has a Vortex Strike Eagle 1-8 mounted on the rifle in good Leupold rings. We've checked that all screws are torqued to spec, checked the rail is tight, shot it off sandbags and the bipod, and have shot several different types of factory ammo through it including 180 gr Core Lokt, 165 Superformance SST, 178 gr ELDX precision hunter, 150 grain Barnes Vortex, and 165 Grain Win Power Points. Both he and I shot it, and the best groups we could get consistently were about 2 MOA with the cheapo Winchester rounds. Very occasionally it shot a nice group, which right now I'm attributing to just luck. Anyone have similar experiences with these rifles, and if so what did you do to fix them? Right now we thing the main culprit is the stock, it seems kinda flimsy even though it is supposed to have a bedding block. We shot it both with and without a suppressor, and with the suppressor it shot a good 3-4 inches lower, as if the weight of the suppressor was enough to bend the forearm of the stock up towards the barrel? Thoughts?
