One of my Son's came by this morning with a new 700 SPS SS chambered in 300 WM. He shot it last week end and ran some Factory RP, Win, FC, and Hornady through it. The glass on it is a Vortex he pulled of of another rifle for now, so we know the glass is fine. He shot it off a lead sled and couldn't get any groups to speak of, it was all over the paper and even off the paper, nothing even able to be considered as groups. He cleaned it about every 10 - 15 rounds.
Last night I loaded up some rounds for us to test this morning, nothing hot, just a mid range average load I've run in other 300 WM's. we swapped the scope just to completely eliminate that variable, yet again, it was all over the place, on and off the paper. Extreme spreads of 12" and more at 100 yds. and barely stayed on the paper at 50 yds..
I looked it over real well and found that that only one lug has contact marks. The stock is supposed to be pressure bedded, but it's only making partial contact and rattles when I tap on it. The bolt face looks like it was finished with a broken piece of glass. So bad it looked like a wash board with raised sharp edges, never seen a face this bad and is leaving major sharp ripples in the primers. The brass has some dig marks, but only on one side, just above the belt. It's round, not egg shaped, and the necks are nice and concentric well centered. The chamber has some very light machine lines, but nothing that would be considered as out of the ordinary for a production rifle.
He doesn't have time to wait on Remington (12-14 weeks) being that he has a hunt coming up before it would get back to him. I've fixed minor accuracy issues many times before, but nothing as extreme as this.
So I can fix the stock issue, polish the bolt face, and lap the lugs, but would like to know if someone here can affirm that one or all of these issues could cause such extreme accuracy issues, and it is extreme.
