I've never found any hunting rifle to outclass the Ultra as an all round hunter. I have 2 here (mine are the SE's) . One probably 4 maybe 5 years old now, bought from new and never touched, the other recently fitted with a Huma reg just because I could. Both are .177 single shot and both perform well above their weight considering the cheap price of the single shot. Both responsible for many many rabbit stews.
As for the kit on them, both are fitted with HW mods ,both have BKL mounts, one has BSA essential scopes, the other has a Yukon mounted for night. Even though they are light weight, both wear sling studs for use with a sling in the field (like a 3rd hand when you need it).
