From a hunting perspective, the HW 77 sliding breech is by far the most practical !
I've used BSA RB2's Airsporters, Superstars and two Goldstars, TX200's but I prefer the wide breech 77 be it a right handed shooter or a left (me)
On a cold winters day out on the edge of the moors clad in fingerless mitts the big breech has it for me !
Same on a 97 but being as the 77 came first, thats the one for me !
