I agree. I dislike bullpups (did i mention that already?
) but the semi-bullpup action seems quite attractive.
High sight lines are fine at range - and in airguns can flatten the apparent trajectory (by which I mean the trajectory is actually the same, but the sweet spot requiring minimal hold over/under coincides with those distances, if that makes sense, albeit falling off quicker as the range progresses) at the crucial 25-35 metre hunting ranges. But at under 15 metres you will find your shots fall 40-50mm below point of aim if zeroed for a “normal” range.
For shorter-range barn/farmyard work, it’s actually hard to beat a short conventionally-stocked rifle. If I was doing that stuff these days, I’d be reaching for my carbined Webley Xocet or BSF B55.
