Well, was at the range this afternoon with my AR-15 with a new Timney trigger in it.  The trigger is the best I have ever had on a rifle.  It felt awsome.  Anyway, I tried zeroing my rifle and it is simply all over the place!  I had a rock solid rest and there was no wind.  

I am concerned that my scope will not hold zero and I need to return it.  I had it pretty well sighted in a couple weeks ago and it was 6 inches high and 4 inches right on my first group.  So I kept on adjusting the turrets and it simply would not hold zero.  Granted it is a Tasco Target/Varmit model that I got at Cabelas for $230.  Just FYI about the scope, I have to press in really hard on the turrets to make them click.  Otherwise they just spin and make no adjustments.

Could it be that the scope is junk or is there something else that could be affecting my groups.  I did not clean the rifle throughout my shooting and I shot about 50 rounds of cheap Remington ammo, so maybe that could be the reason?  My barrel is a 20 inch SS bull barrel, so I don't really think it is a hot barrel.  

Any suggestions would be much appreciated.  Thanks guys!

i would try some quality ammo first. if it still shoots like crap it may be the scope.

Thanks for the suggestion.  I don't know if good ammo would be the answer, but I will definitely try that out.  Thanks again.

Trash-co scope.

Get rid of it.

Try another scope off of one of your other rifles.

Zero with the rifle sights first. It sounds like your rifle scope isn't reliable as others have said.

Maybe it's the "rock solid rest";  try shooting with iron sights in prone with good ammo.

You didn't really specify what you were using for a rest, but if you're resting the rifle against anything hard the rifle could be bouncing around when you take a shot.  I agree with curiomatic when he said use irons from prone.  The only thing I can add to that is to use a good loop sling as well.  With a good bone-supported prone position and a tight loop sling, and if you achieve a good NPOA, you can shoot that rifle like a machine out to as far as you can see!
