I have one wearing a Leupold VXII 2-7 in Leupold QR mounts with x-Low rings.
Easily shoots into 1/2" at 50 yards with good ammo, and,
if I do my part, "1 holer's" that you can cover with a dime.
Very satisfied with it. Liked the looks and finish of it more than
the CZ 452.
Yes, there is a set screw to increase/decrease trigger pull weight. Satisfactory at the lightest setting.
The magazine has so far cycled probably 1000 rounds with
no problems ... and I have two "spares" as well.
It likes Eley Tenex Ultimate EPS & Lapua Midas M (both pricey) and Lapua Super Club which is moderately priced. Of the more conventional stuff CCI "Green Tag" works well too !
