Snood,
I had one of these in 308 Win back in the 80's. I sold it, and a bunch of other guns, to generate money for college. It is the only gun that I sold that I wanted back and couldn't get back. My Dad bought the gun new (it was many years old, but new in the box) in the 70's. We didn't do a lot of shooting with it (I'd guess that we put 3-4 boxes of ammo through it), but it never failed to repeat. I believe that we fed it Remington Core-lokt. I can't give you details on accuracy because I didn't have a lot of time to spend on that stuff then. However, I can tell you that the groups were acceptable to us at the time and it killed every deer that it was pointed at - some at fairly long range. My only caution to you would be that buying it, like anything that is no longer in production and has little or no support, could leave you with a non-functional gun at some point.
When I owned the gun I called H&R to ask why it was no longer available (because we had such a good experience with the one we purchased, and it was so much better looking than anything else on the market). The customer service person said "that gun had some problems so it was discontinued". At the time I wondered if the problem, like a lot of H&R guns from the 60's, was that it was built to such a high standard that it couldn't compete with Remington's offerings.
One last thought - you may want to check with gunparts corporation (they are on the web) to see if they have any parts for the old girl. They may also know, due to demand, what, if any, problems the gun had.
Good Luck.
