I agree with therewolf on a copper fouled barrel.That will really affect accuracy. If your have any green or blue colored patches when you clean your barrel,it is copper fouled. There are many good solvents on the market to clean the copper from your bore,and since this is a new rifle,that could be your problem.

You also said you shoot the rifle better prone,than from a bench. Your line of sight through the scope changes when you change your shooting position,and that can also cause accuracy problems.You need to keep the same cheek weld against the stock in order to shoot the same in different positions.That just takes practice,and you may need to get a cheek weld pad for your stock to help you with that problem.

MOA = Minute of Angle. A circle around you is divided into 360 degrees. Each degree is divided into 60 minutes. Of course as you get farther away from the center of the circle both the degrees and minutes get wider like a piece of Pizza (dang pizza sounds pretty good right now). At 100 years away from the center of the circle a minute is 1.047" (MOA). At 200 yards its twice that and at 300 yards 3 times that etc. Most people just round it to 1" and call it good. Canebrake gave a course on this in one of the stickies.

Gun confiscation will not happen in my lifetime.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience."

When I clean the rifle it does not show the blue or green patches, it is black brown. Before I bought the rifle I saw a shooter with the same rifle and when he cleaned it, the patches were blue like you said but mine does not have that.

You need to use a copper solvent to get the copper fouling out. It will be similar to other solvents, but it has ammonia in it to dissolve the copper. Hoppes makes a copper solvent. I usually use Shooters Choice copper solvent.

MOA and 1" are two separate measurements and MOA is slightly larger than 1"!!!! Get your facts right people!!!

As string1946bsaid above, an MOA is actually 1.047", but most just round it off to 1". I doubt any of us are concerned or can even measure the 47 thousands of an inch difference when we are talking the center of one ragged hole in the paper to another ragged hole.
