I've owned a Hortisia since May last year, I have the longer one 220/450 and can wholeheartedly recommend them.
They are a very good rifle and not just for the money. The gun that I own has the standard in house barrel and is every bit as accurate as my other two rifles, those being a AA S410 and a HW100.
It also has a great shot count. When I shoot it it just feels right and sits nicely in my shoulder.
If I have a niggle it's with the trigger, there's not much of a first stage. It actually breaks like glass with no creep but personally I'd like a bit more first stage.
The only problem that I've had in the year that I've owned it was a stiff cocking bolt that was easily cured by a clean and very light re-lube.
Hope that helps. All the best. Steve.
