am i correct on saying that on an aluminum bedded stock the take down screws should be torqued at 50-60 in/lb? whats the rule of thumb on that?

Re: torque on aluminum bedded stock
65 inch pounds is the standard for aluminum bedding blocks and pillar bedded rifles.

Re: torque on aluminum bedded stock
50 in lbs on factory bottom metal and screws. Yeah you can get away with 65, but repeat 65 with factory components and you better have back ups on hand.
50 has been a good standard and no benefit has been noticed going beyond.

Re: torque on aluminum bedded stock
now do you guys recommend trying diff torque settings and shooting my rifle to see what it likes? or set it to 65 and be done with it?

I'd call a couple of the standout gunsmiths (Terry Cross, Surgeon, Alan Warner etal..) around here (maybe via PM) and be done with it. I shoot a Surgeon action, so I called them and got "about 50inch lbs."...I went with that and never looked back.

Re: torque on aluminum bedded stock
as long as you always use the same torque everytime be it 50 or 65 it should be fine

Re: torque on aluminum bedded stock
If you’re running a factory Remington bottom metal (aluminum) 35 to 45 inch pounds, much more than that and it will start galling and/or stress crack over time... Ask me how I found out!
Pillers or bedding block doesn’t matter. The bottom metal is a cheap piece of aluminum.

I have had great luck over the years with 45/front and 30/rear with Rem. BDL
Set-up. Hope this helps. Paul.

Re: torque on aluminum bedded stock
My handy little holo krome screw chart and a little interpolation says that 65 in-lb on a 1/4-28 screw into a lubricated hole will result in 1142lb of tension in the screw. At 50 in-lb, 878lb tension. It seems to me that the thin factory aluminum bottom metal would have a hard time at more that 1/2 ton force on each screw.

Re: torque on aluminum bedded stock
The instructions that came with my McRee specified 65 in/lbs of torque for the action screws. For sure, it's a chassis vs. a pillar-bedded system, but 65 seems to be a common number for aluminum pillars or chassis setups.

Re: torque on aluminum bedded stock
I think that playing with the torque modifies the barrel harmony. It could be a good way of getting better accuracy with factory ammo. But you can also just torque it to the recommended setting and match your loads to a given harmony (ladder testing). But what I just said needs to be confirmed by someone who has more expertise than I have.

Re: torque on aluminum bedded stock
Another thing to think about is caliber. Are you shooting a .338? .338 would require 65, I am assuming youre in the .308 range and with stock bottom metal, I would start with 50 and maybe in 5 lb increments shoot and see. A few have said it before, you may start to fuck up your metal. Im a dummy and thats what I did. I tuned it back to just 35 on my B&C and it shoots the same (savage .308). Just saying take peoples experience and learn from that before you follow and do the same dumb mistake.

Re: torque on aluminum bedded stock
If 65 could damage the metal on a 308 it could also damage the metal on a .338. My 308 Savage 10FP is torqued at 65 in a B&C medalist and I haven't noticed any damage to the metal.

Re: torque on aluminum bedded stock
I have a 700 LTR in .308 mounted in a B&C Varmit/Tac stock. The LE armorer who originally built the rifle gave me a sheet with all the torque values he recommends for the rifle. For the main mount screws: 65 in/lbs.

Is this with the stock bottom metal? I've had mine at 65 inch/lbs. for the first 15 rounds and have now backed it off to 50 due to concern over the strength of the stock bottom metal. I'll be hitting the range tomorrow to see if it had any impact on accuracy.

Re: torque on aluminum bedded stock
fwiw - I've tested this with several of my rifles and with good pillar bedding, tighter than 45 in/lbs did not make it shoot better or worse. Tight is tight and more than that just is hard on threads and components.
I put a drop of oil on the threads and torque to 47 in/lbs, it is repeatable every time. I can take my action in and out of the stock and maintain zero. My calibers range from .223 to 300WSM.

Re: torque on aluminum bedded stock
i torqued it to 65 and did a ladder test and didnt notice anything wrong with the bottom metal i guess i could back it off to 50 or so

Re: torque on aluminum bedded stock
If you are using a factory remington action and factory bottom metal/screws, stay with 45 (factory recommended).
If you are using aftermarket bottom metal and action then you are probably fine going higher.

No - aftermarket bottom metal. First it was with a stainless steel floor plate magazine/trigger guard. Now I'm using a CDI precision setup. It's a good point, though - not all bottom metal is the same.
