Kart29...From your previous post it sounds like there could be several problems to check...
1> Bad scope, not likely, Bushnells are usually pretty good, but still possible.
2> How's the trigger? Maybe a trigger hone will improve accuracy. See the Perklo link in the FAQ and Raynor's trigger hone sticky in the Misc H&R Talk forum.
3> Are you following thru with trigger pull? The transfer bar requires a full pull to the rear at the break to allow consistent pin strike.
4> Are you getting vertical stringing? How are the first 3 or 4 shots from a cold barrel?
5> Make sure the scope rail is mounted solid. I remove the factory mounted rail, clean the mounting holes in the barrel, then remount it using loctite.
I'd clean the bore real well until there is absolutely no jacket fouling present, then shoot a few fouler shots, let it cool and try from a cold, fouled bore with the win white box 45gr JHP. If it still doesn't shoot well, contact H&R and ask em to fix it.
There are way too many .223s here that shoot moa or better to accept what you are experiencing, if it won't shoot good no matter what you try, let H&R know about it. They can issue a call tag for pickup or reimburse you for shipping it to them. Right now is a good time to let them work on it, they are not busy at all in comparison to past experiences reported and they do warranty quicker than barrel fittings. FWIW, they received my frame for a barrel on May 23rd, they shipped it back to me on May 31st!!
