I bought this Beeman R7 (HW 30) over 30 years ago for $159. I still have it and was shooting it yesterday to check the zero with some of those lead-free Gamo pellets. It did not care for those Gamo's, but it will still shoot one ragged hole, at 30' all day, with lead wadcutters.
I used it to dispatch a couple of rogue rabbits that were enjoying my pea patch too much this summer.
I figure it has had ~10,000 pellets put through it, so I was thinking of getting a tune-up kit for it next year.
BTW, this sub-forum was a great idea. I am looking forward to browsing about to see what folks are using these days.
