Welcome to GBO and the wild world of handi's , if your going to send it to H&R anyhow i'd let them fix the problem . might give their CS a call , maybe they will cover the shipping to get it there as a factory repair and then get the 223 added while they have the rifle , just an idea .
You may just need to give the chamber a good polishing to cure the problem , that is a easy fix . its in the FAQs at the top of the CF Forum .
And yes there are a few Ok. boys here to say the least . Digger , lik2hunt ,warf , just to list a few . i'm sure they will be droping in .
