I had a Savage model 110 that I did allot of work to, rebarreled, new stock, muzzlebrake... This gun is a consistent half moa shooter. I wanted to put a 20 moa rail with some good rings on it. When I took the leupold rings and bases off, I noticed that the base holes were out of line. I figured they were drilled off center from the factory so I took it to a local gunsmith to have it tapped to 8-40 and centered up. He's had it for two month's so I called him yesterday and asked him what the deal was. He said he just finished it, and the holes weren't off center, he put it on his press and used some sort of alignment tool and the action was actually bent. Said the front of the action was bent about half a screw holes width. I personally have a hard time believing this because the gun shot so good and the bolt cycled fine. I dont know how many thousandths half a 6-48 screw hole is but I'm sure its enough to cause rifle not to bolt. He said he straightened the action and tapped the screw holes out to 8/40 (ouch). I just wish he would have called me because I probably would have wanted to sent it back to savage. I am assuming that the bedding needs to be drilled out and redone. What do you think?

I think he lied to you.

If it drops right back into the stock, you know he lied....
 
Re: Was my ACTION BENT?

it's not out of the ordinary for an action to warp slightly during heat treating... in my experience Savages aren't usually that far out, but it's possible, 1/2 a 6-48 isn't much over 7.5-8"...

I do serious doubt he really "straightened" it, likely he trued the face of the action and redrilled the holes.
 
Re: Was my ACTION BENT?

It's certainly possible, and wouldn't necessarily affect accuracy.

As an old grizzled gunsmith told me "The receiver lugs and bolt lugs are what locks up the action, everything past that is just extra stuff hanging off the end sonny."

If the barrel and bolt face were aligned, nothing else really matters (to an extent). This may be a case where the floating bolt head of a Savage action proves it's design value...
 
Re: Was my ACTION BENT?

we have had bad luck with some of the recent savage 338 Lapua 10/110BA rifles that came into our shop- 2 out of 5 have had incorrect head-spacing issues (could not even chamber a round) - we had to send them back to savage & wait 1-2 months for them to send out new rifles in both cases.

The other savage rifles that haven't had head space issues have shot sub-moa and we have been very pleased with them.

Did you actually check with a gauge, or just with ammo?
If it was truly short on a gauge, why didn't you just crack the barrel nut loose and re-adjust the headspace.
If it was correct on a gauge, then the ammo or the actual chamber dimensions are suspect...
 
Re: Was my ACTION BENT?

If I had to wager a guess (always dangerous without the part in front of me), it's more plausible that the action was twisted rather than bent. The twist could have come about during the original heat-treat, or through some ham-fisting during the rebarreling process. That amount of twist is around a few degrees; it wouldn't surprise me if the Savage trigger group was tolerant of this misalignment (I've never found the pre-Accutrigger setup to be particularly fussy).

Regardless, I do hope that the misalignment was properly diagnosed prior to attempts at "fixing" the receiver.
