Torque specs for piller bedded actions

[halfmoanut]

Does anyone use a torque wrench with specific weight specs when reassembling a barrelled action into a pillar bedded stock? If so what for front screw, rear screw?

talk to the action maker
then your gun smith
you need to tell us more about the rifle...action stock type of shooting chambering

35 to 50 inch pounds is pretty common. Exact torque isn't as critical as all the screws being the same torque.

If the bedding is right it doesnt matter

 

[Tommie]

I usually tighten until the threads strip then back out a quarter turn.

And never forget that cross-threading is nature’s LocTite

65 inch pounds is what my research showed,that’s what I use on bedded Borden actions on LRB Mcmillan benchrest stocks,,,I use the fix it sticks

 

[rijndael]

I've always had good luck with 55 inch pounds on the front and 50 on the rear. I've done this going back to my days with HS stocks and factory 700 actions. It's served me well and I don't have much need to deviate.

On factory actions I've played around with different torques, but not on my custom actions, they've always shot well enough that adjusting that seemed like it wasn't low hanging fruit.

Yes. For the love of all that is holy, yes torque to specs and above all be repeatable.

If so what for front screw, rear screw?

Depends on the action, and the stock/chassis, etc.

Some time ago, I spoke to Dolphin Guns about my chassis. Mik suggested that 55in/lbs was good, but not much difference was noticed between 35- 55in/lbs. Below 35, some shooters had noticed the screws loosening off.

 

[Dusty Stevens]

73 dry and 65 lubricated is the torque spec for 1/4-28 bolts in stainless. There should be no difference in the front or back IF it is bedded correctly- they are the same size bolt

My Savage actions, i do 30 inlb on the front screw, rear screw 15 inlb.
Then i tune it 5 inlb at a time to 30 inlb per the action screw tuning article on this site.
One of my rifles likes 15 inlb. One 20 inlb. One 25 inlb,

Let the rifle tell you.

Yes Sir, grab the long end just like that!

 

[boltfluter]

I use 45" lbs in front and 30" lbs in the rear. Has never failed me over the years and have never had one come loose.

[Mr. Ten-X]

Have used 55 inch pounds for just about ever.

 

[RussellJ]

I have a DVD on pillar bedding stocks. On the DVD Darrel Holland says 30 -35 in lbs of torque.

Mr. Taylor,
When you hit the designated torque what clicks, your allen wrench or your finger joints!!!

Mr. Taylor,

When you see my arteries showing in my hands it’s a done deal.LOL
Now the torque is perfect!!

 

[shoobe01]

Very much like the "torque until the bolt shears, then back off half a turn" advice.

Question came up at the range one day while doing some other adjustments to another shooters rifle , and I suggested , "Give McMillan a call ". McMillan said 45in/pd. on their stocks . That's where it got set at , and all the sudden , his "Flyers" disappeared . Hmmm . Maybe they got sumptin there .
