I received my new model 12 vlp dbm .308 Win just before Christmas. Out of the box, I discovered a problem.

I first shot PMC 147gr factory ammo. No problem. Shot great.

Then I used a few handloads with 155gr Nosler Custom Competition. Two or three firings resulted in stuck cases.

I then used handloads with 168gr Sierra MKs and Nosler CCs. About 30-40 percent of them would not permit the bolt handle to lock down, as if they were too long. Of those that did fit, a few resulted in stuck cases. Powder was 41gr of IMR 4064. Lyman book says 40 is the starting weight. All were within spec. Bump gauge and caliper showed this. I always ensure my empty cases will chamber before I install primer and bullet.

I then tried a box of Silver State Armory (SSA) 175gr factory ammo. None of the 20 rounds would allow the bolt to lock down.

I also have a Savage model 16 in .308 Win. It has an identical action, but it does not have the bull barrel. All of the rounds mentioned above that would not allow the bolt handle lock down in the model 12 worked just fine in the model 16. I'm no gunsmith, but it's as if the barrel was screwed in a bit too far into the action, thus shortening the available chamber length.

Do you guys have any thoughts or suggestions before I call Savage next week? I appreciate your expertise.
