LarryR, I hate to be the bearer of bad news, but if that is a H&R/NEF Handi Rifle in .223 (as long as it's not the superlight) and after you hang around here a bit and learn to tweak these little guns you will still have a problem sighting in your .223 at 50 yards.
I can see it now, set your target up at 50 yards, carefully and slowly shoot 3 to 5 shots of cheap Winchester 45 grain HP Value pack ammo at the target set up at 50 yards, check the target and only see one hole on the paper. But there is the good news to go along with that one hole, all the bullets would have gone through that single, one hole!!!
Stay around a bit and I predict that gun will be shooting great. If not and there is an inherent problem with that particular gun another good point is H&R will most likely fix it or replace it for free!!
, Oh and by the way, Welcome aboard!!!....<><.... :grin:
