300 Weatherby Mark V bolt torque specs
- Thread starter Mudduck
- Start date
Per the Weatherby web site:
Screws for wood stocks have a torque specification of 35 inch pounds. Please note, however, that you should tighten the rear screw first and then the front screw.
If yours is a Fibermark® or an Accumark® stock, the torque specification is 55 inch pounds.
The correct assembly procedure is:
1.Tighten the rear trigger guard screw first to 30 inch pounds.
2.Align the barrel to the center of the barrel channel in the fore stock.
3.Tighten the front trigger guard screw to 30 inch pounds.
4.Tighten the rear screw to 50-55 inch pounds.
5.Finally, tighten the front trigger guard screw to 50-55 inch pounds.
Applying this method, using a torque screwdriver of the proper size, will insure the proper fit between the receiver, and custom aluminum bedding block, as well as the proper positioning of the barrel in the barrel channel.

Thanks Ohdot
I found the same info for the Ultralight. I was concerned because the barrel on the ultralight isnt freefloated. ( apparently they dont freefloat the barrel on the ultralights because it heats up if you take a few shots in a row and this supports it much better)??
I have never had a rifle with a barrel this skinny. If it didnt have the fluted barrel I would be very concerned about accedently bending it while tromping through the bush .... and without the muzzle brake ... Im not certain I would want to pull the trigger on something this light.
Cant wait to work up some loads for it and get out and do some practice shooting with it ... however its been suggested that I also bring along another rifle to shoot in between shots while the barrel cools down
I've wondered about the rear screw first thing in the Weatherby manual. Doesn't everyone else in the world say snug the front screw first, then snug the rear then go back to the front and give it that last bit?
