If you want the most accuracy your bolt action rifle can give you, then this follow up article will help you make the last changes you need to perfect your long range precision rifle weapons system.
In the article linked earlier, I talked about the importance of action/stock assembly rigidity, as well as how to make the stock capable of supporting the amount of torque needed. In this post, I’ll focus on ensuring the proper torque on your action screws, adjusting the cheek rest, and working on the trigger.
Action Screw Torque
The torque applied on the action screws is crucial to determine accuracy and point of impact consistency. You can’t just screw in the action to the stock on a precision rifle. Screws must be tuned, like the strings of a guitar. For this purpose, you’ll need a torque wrench, since the applied torque must be both precise and uniform. Torque must be checked regularly (I do it before any shooting session, preferably after the transport), and the same amount must be re-applied every time you disassemble or reassemble the rifle.
The range of optimal torque settings varies depending on the stock conformation and material, the presence of bedding and pillars, and the conformation of the action. For standard commercial rifles, the manufacturers usually share the optimal torque settings for their products on their website; however, although you might be able to dig up the relative information for customized rifles on the ‘Net, you may have to find out the correct torque settings from your gunsmith. For example, for a Remington 700 with a synthetic stock and an aluminium, integral bedding (like the Remington Police), the torque settings for the three action screws are: 55-60 in/lbs for the front screw, 40-45 in/lbs for the central screw, and 22-24,5 in/lbs for the rear screw. You can try to find the best settings in the given range yourself; it could even improve your accuracy a little, but the process is also time (and ammo) consuming. The key point is to make sure you always apply the same amount of torque for a given range.
