DGrig, you can check these couple of things first, look at the crown of the muzzle for any burrs or deformities, if you can see a carbon "star" or discoloration in that stainless muzzle it should ideally be even all around. Check the forearm and see if it is binding or pressing on the barrel on one side more than the other, try the gun with an o-ring over the barrel/forearm attachment stud to assist in "free floating" the barrel or use a piece of business card between the bottom of the barrel channel in the forearm and the barrel to prevent the barrel from contacting the forearm. ALSO, very important, be consistant in your trigger pull, pull the trigger fully to the rear each time without jerking, just don't "trip" the trigger. Be sure you settle on a particular load and don't keep jumping around from load to load, especially on one target string. Different loads will shoot to different points of impact. Try some of the Winchester Value Pack 40 or 50 round HP 45 grain "Varmint" ammo. Wal Mart has it for about $14 for a 40 round box. It has become the "Gold Standard" for shooting out of these H&R .223's...Good Luck and let us know how things work out....<><.... :grin:
There are other things to try which might also help but these are the easiest and therefore the first to try and should help. If all else fails, sell me the gun!!!! (seriously!!!) :grin:
