[QUOTE="Frog4aday, post: 1599212, member: 9308"] Since I brought up TORQUING things correctly, here is some info I've gathered and saved over the years. Maybe it helps others: [B]Torque Specifications for Gunsmiths[/B] [I]By Eric Kiesler from BROWNELLS[/I] [B][U]Action Screws:[/U][/B] · Remington - “no more than 45 in/lbs” on the action screws of the 700 VS o ([U][I]10-15 in/lbs on the standard 700)[/I][/U] · Weatherby (65 in/lbs). · Winchester (25 in/lbs) · HS Precision (45 in/lbs) ==================================================== [B][U]SCOPE BASES & RINGS[/U][/B] From [B]Leupold:[/B] [LIST] [*]Base screws 14 in/lbs [*]Ring screws, 15-17 in/lbs [LIST] [*]45 in/lbs on the windage screw [*]65 in/lbs on the cross bolt for the Mk IV ring [/LIST] [/LIST] From [B]BURRIS (for Signature Series rings w/plastic inserts)[/B] · Ring Tops - 18-24 in./lb. · Bases - 28-32 in./lb. o Rear windage base screws - 40-45 in./lb. [U]For other Burris products[/U]: Eliminator® / LRFP Base Clamps: 40 inch-pounds Signature / Zee Ring Tops: 20 inch-pounds Signature / Zee Base Screws: 30 inch-pounds Rear Windage Base Screws: 40 inch-pounds AR-P.E.P.R.™ / Tactical Ring Tops: 20 inch-pounds AR-P.E.P.R. / Tactical Ring Crossbolt: 65 inch-pounds Signature Rings™ Clamps: 30 inch-pounds Rimfire / Airgun Rings: 20 inch-pounds [B][U]Rifle Action & Scope Mount Torque Specifications; for two or three receiver SCREW ACTIONS[/U][/B]: First ensure that the recoil lug is seated securely against the stock by just lightly tightening up the front receiver screw then gently but firmly bumping the butt pad against the floor. Next, tighten up the [B]front[/B] (one or two) receiver screw(s) to [B]20 inch pounds[/B], then work up to 30 inch-pounds in 5 inch-pound increments, and always tightening the front screw first and then the second screw (if there is one). Once the front two receiver screws are torqued to the final torque setting, I will [B]set the rear receiver screw to 5 inch-pounds [/B]and shoot a 5-shot group [to evaluate accuracy. Increase Torque Incrementally on Rear Action Screw After the group is shot, allow the rifle to cool off to about the temperature that the first group was shot at then add 5 inch-pounds to the rear receiver screw and shoot another five-shot group and allow the rifle to cool again. Repeat this process until you have tightened the rear receiver screw to 40 inch-pounds or have seen the groups get smaller and then start getting larger again. Once you have seen the groups decrease and then start to increase in size then you will have found the area of torque to work in. You can then fine tune this to the exact inch-pound torque settings[B]. *** 15 to 25 inch pounds is the ‘sweet’ zone[/B], usually. =============================================== [B][U]From Wheeler Fat Wrench instructions:[/U][/B] [SIZE=3][B]What torque should I adjust my fasteners to? [/B][/SIZE] Always refer to manufacturer’s specs, but we recommend: · Base Screws 30 inch-lbs · Ring Screws ([B][U]aluminum[/U][/B]) 10 -15 inch-lbs · Ring Screws ([B]Steel[/B]) 15-20 inch-lbs · Windage Screws 30-40 inch-lbs · Guard Screws: o (with bedding pillars) 65 inch-lbs o (no bedding pillars) 40 inch-lbs *note: middle guard screw should not be torqued [/QUOTE]
