I put a Shaw bbl on the Ruger 10-22 and a Magpul stock to hold the bull bbl. Scoped it and find the scope runs out of adjustment and it shoots about 5" low at 50 yards. now i hear about the famous barrel droop on 10-22's when you tighten the screws that hold the barrel in place too much. Supposed to be about 10-12 inch pounds. Now the question. Shooting the gun, it shoots great. less than 1/2" at 50 yards. I think I can get it to 1/4" if I work on it. Wondering, since it shoots great as is, I can cure the droop problem by buying a new scope base that has a 20MOA tilt to it and correct the problem with the scope. Which way is best, go back and reinstall the barrel and tighten it to 10-12 inch pounds, or leave it alone since it shoots good, and change the base.
