If memory serves, James, you already have an HW 35, I believe it's basically the same gun as the R7. The HW 77 is a whole 'nother critter. Fixed barrel, underlever, very accurate and smooth. Has a reputation for NOT being hold sensitive, although that wasn't true in my case. If you intend on putting a scope on it, I'd suggest you go with the 97 rather than the 77. Although I like the classic lines of the 77 stock better, it doesn't scope as well, and the 97 stock just fits better IMO. Otherwise, essentially the same gun. Looks like you already have a nice collection of break barrels, maybe this is the time to add a fixed barrel to the line up :-). Almost forgot, the 77/97 packs more punch, I was getting right at 15 fpe with mine after a tune (busted spring when I got it, used). Later.
