Barrel threading risks?

[toshu]

I have a Savage 110FP that I was planning on sending to SRT Arms to be threaded and shortened in order to be able to mount a Shadow TI suppressor i ordered.

With the right shooter, it is a 0.25 MOA rifle. Although SRT Arms has done Savage barrels before, i have a friend who has warned me that disassembly from my Choate stock, and more importantly, removing the barrel may screw up the accuracy. His opinion is that it may not be torqued exactly the same way when reassembled and this may change the guns accuracy.

For those of you that have done this with a Savage, whats been your experience

So long as the smith knows what they are doing you will be fine. I have had FN’s and Remingtons threaded without issue or accuracy flaws. Savage should be no different.

...and this may change the guns accuracy...

True. It will change the accuracy. You'll have to re-zero it.

Changing the precision? Hell, it may come back better, as the barrel will be stiffer, and if the smith does a really good job on the crown.

Theoretically accuracy will change but could be for better or worse. You are shortening and re crowning the barrel, that will change barrel harmonics and bullet speed for sure. I would be less worried about barrel torque.

You're not likely to notice a difference. Not apples to apples but I have tried hand tight through as tight as I can get my Barloc with no perceptible change in precision or POI. My experience previous to the Barloc has been anything from 20 to 100 ft lb shoots about the same.

I'd be less worried about nut torque than stress relief in the barrel. Removing material in an improperly stress relieved button barrel will cause the muzzle to trumpet out a few thou and accuracy goes to pot.

Thank you gentlemen, for your responses.

That's a pretty awesome test, good data to have.

Not barrels per se, but reminds me of the time I simply could not get on at 500 yards, but the gun had been great earlier, and the week before when practicing for the match. Turned out the (very good, but will remain unnamed) shop it had recently been to had finger tightened the action screws (yes, yes, I should have checked! lesson learned). At the match, the screws finally backed out to fully wobbly, and my accuracy dropped. But until then: still a better than 1/2 moa gun that held the zero.

When I fixed it, I did the usual super-careful with the torque wrench but, once assembled safely and to the degree it won't fall off, torque... doesn't matter???
