Hands down Ruger! ! Most dependable. I've had a bunch of them. They really like heavy bullets I'm not much of a shot but most of them would shoot 1" or better at 100 with factory and smaller with 275 or 300 grain handloads.
I have a Winchester 338 Mag Extreme Wheather. I had problems with ejected shells staying in loading port, mag box is to short for any seating depth adjustments and accuracy problems. The muzzle measured .590 which is very skinny and the bore is pitted. Had to mill ejection port larger, Wyatt's extended mag box and am rebarreling it. Definitely not what I expected and even without the new barrel, would almost be approaching custom rifle expense.
