Yea it's kinda the nature of the beast when you are dealing with a super proprietary gun. I dont blame them either; I would never trust a consumer to properly head space a bolt. Even with a KAC though I could find and buy a SR25 bolt ($580) if I really wanted to have a spare. I think the problem I am having really comes down to tolerance stacking, and I will probably send the gun back next week. I seem to be the first person to report this problem on the internet and dont know if its inherint to the MSR 10 line up. I doubt it though and will report back how Savage takes care of it. Sucks when you actually shoot guns and dont just look at them like most gun owners.
