Accuracy issue with 700 Alpha 1 in 308
I bought this rifle new earlier this year, and had it to the range a few times. I can't seem to get groups that I like at 100 yds, and I don't think it's me. I ended up buying a lead sled to try and eliminate myself as the issue as much as possible, and took it back out this weekend. Best group I could get was around 1.75", with Federal Gold Medal Sierra Matchking 168 gr. I've tried several different types of ammo (Federal Premium Gold Medal Center Strike 168 gr, Federal Premium Sierra Matchking Gold Medal Match 175 gr, PPU Match Line 175 gr, Hornady Superformance Match 168 gr) and what seemed the most consistent was the Federal Gold Medal Sierra Matchking 168 gr. I shot the first 4 groups on the lead sled (left to right, top to bottom) and the last 2 on a bipod. Looking for suggestions to help improve the performance here, or is this what I should expect out of this rifle?
I was making a few scope adjustments along the way. I accidentally went the wrong way with one, hence the flyer on the bottom middle of the top center target.
