Wood only stock?

Pillar bedded?

Full bedding block?

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Varies by mfg'r. On Remington 700's and Mausers I go 38 in lbs on the front and 28 on the rear.

Who gets to decide what the proper torque is?

I think that is his question, are there standards?
What is recommended?
What is the source or reasoning of the recommended torque....?

Good question Mike I too am curious.

I have a synthetic stocked pillar bedded 30/06 that I want to use as a "takedown" rifle for travel purposes merely by taking the rifle out of the stock allowing me to put it all in a shorter case.
I'll be experimenting with the "proper torque" so it has repeatable accuracy.

Dave,

Yes, those are all my questions or are there rules of thumb for stock, bedding, action types.

Near as I can tell, everyone sort of makes up their own. I tighten them as tight as I can get them without doing damage to the screw head, the thread and whatever is getting squitched in between. Some screws I make finger tight. Some you need a jack hammer to get loose. I'm very powerful, for a little old peckerhead!


When I was a kid. I had the stick. I had the rock. And I had the mud puddle. I am as adept with them today, as I was back then. Lets see today's kids say that about their IPods, IPads and XBoxes in 45 years!

The nice people at FN Winchester specify, in the manual, 35 in/lbs for each screw regardless of stock.

Savage states 30-35 in/lbs for non-accustock, and 40 in/lbs for accustock. I don't go over 30 on the back screw of a Savage 110. The back of the action is poorly supported and they warp very easily. I usually do the front at 50 in/lbs, but mine are all in aluminum bedding block stocks.

Remington lists no torque in their manual. 35-40 seems about right.

Howa says nothing, but tighten firmly.

Weatherby, for both Vanguard and Mark V, says 35 in/lbs for wood and plastic stocks, 55 in/lbs for aluminum bedding block stocks. Tighten rear first.

That covers the manuals that are in my desk drawer.

They are better than many manuals and cover disassembly of the whole rifle including bolt. Along with tips for different weather conditions, like completely degrease the bolt in freezing temperatures.

This I learned an hour or so ago when I wondered if they had torque values in them. Until then, I had just thrown them in the bottom drawer of my desk and not opened them.

Should be put into a chart and made a "sticky" up there with speerchucker's post. Thanks for the research guys.

God Bless, Louis

Doesn’t Ruger specify a very high amount of torque for the front action screw? Something like 90 in/pounds? I mean on the M77.

I am certainly no expert.

But, I tighten them as tight as can, without causing any damage.

And that goes for all screws on rifles and scopes.

Thanks for saving me the money guys! I was about to buy one of the inch pound torque wrenches. Not needed now.
