Gun accuracy after cleaning

I have had a Ruger 10/22 for a few years now and it is my favorite plinking gun...but I have noticed that it shoots differently everytime I take it appart and clean it...I guess my question is does the amount of tork on the screw that holds the barrel to the stock and the amount of tork on the barrel band effect accuracy? If so, how would one tork these to the same tolerences everytime? Also, I have switched stocks 2x...the oe stock was the synthetic...I got a new wood stock for it plus I have a folder style stock also...I expect a little difference between stock to stock but should I see it everytime I clean my gun? Any advice from the expertz would help greatly!!

Thanks in advance!!

  I also have a ruger 10/22 and have also noted the same variances in point of impact before and after cleaning. the answer is yes, the amount of torque applied on the screws will play a role in accuracy and point of impact. my very basic method of keeping the same torque is to make a small white mark in the screw that lines up with one on the band/stock. everytime line them up, screw it in, and count the same amount of rotations until it the marks line up with sufficient stiffness. not high tech, but it seems to work for me. hope this helps

  CWIN thats a very good idea Ruger has a torque setting which can be obtained from Ruger and they sell torque tools at Brownells,and some sporting goods stores.
  
  Best!!

  a small, high quality torque wrnech, will be the most precise. CWINN's plan will work also. Taking a rifle out of the stock, ANY RIFLE, will always affect point of impact.
  
  If you use a torque wrench, be sure to work back and forth from screw to screw, increasing torque gradually, just like head bolts or intake bolts on a motor. This will help to lay the rifle in the stock with the same, even pressures each time.
  
  A great rifle with a junk scope,....is junk.

  I have encountered the same with torque, on the screws.
  I have noticed, my rifle having being shot about
  5000 times, does not like the hypervelocity loads.
  It just does not group with those babies.
  Standard and regular high velocity, are the ticket.
  40 grains, nothing less...

  Good idea Robsguns. Looks like I might have another project to undertake.

  Are these 10-22 accuracy variations when using iron sights, scopes or both?

  Mine is scoped...but the point of impact on mine usually varies from left to right so I'm thinking it's the barrel band...I'm thinking about building a new 10/22 using Volquartsen parts...ie...trigger,barrel,bolt/receiver on a Fajen stock with a BSA scope...I plan on having it bedded so I will be more precise on the torque tolorences then...should only have 1 to worry about anyways...the bolt that holds on the barrel...10/22's are cool!!
