Finally got back to the range yesterday to really start wringing out the new Mossberg MVP. I hope to get good conditions Friday to do a little work at 200 yards, but here are the accuracy results I've seen so far. These are averages of three three-shot groups at 100 yards from a Battenfeld Fire Control rest. Velocities are averages of 10 shots measured 12 feet from the muzzle.
Hornady Superformance 36 gr. NTX, 3,615 fps, 1.15 in.
Hornady 40 gr. VMax, 3,510 fps, 0.76 in.
Black Hills 50 gr. VMax, 2,942 fps, 0.46 in.
Federal 55 gr. Sierra GameKing, 3,118 fps, 1.12 in.
Black Hills 55 gr. Barnes MP, 3,100 fps, 0.60 in.
Federal 55 gr. Ballistic Tip, 3,048 fps, 1.03 in.
Winchester 64 gr. PowerPoint, 2,937 fps, 1.01 in.
So far the Black Hills 50-grain VMax takes top honors. That's the one I'll shoot at 200 if I can. If I get the chance I'll test a couple more loads at 100 too—although I may not be able to as I have this rifle for only a few more days because it has to go out for photography.
Other observations: The 13-inch LOP combined with a light buttstock takes a bit of getting used to in terms of weight distribution on the bags. The trigger, which I adjusted to 2.5 pounds, is pretty darned good. Very consistent, with only the slightest creep.
