Weihrauch HW 97 accuracy at 25m

25 meter distance shooting accuracy for Weihrauch HW 97 SPRING air rifle, uploaded by Igor, at November 5, 2017. Test ID: #15 (SPRING = Spring powered)

Average accuracy for tested HW 97 airgun is 1.4 cm (≈ 0.5 inch) horizontal and 1.9 cm (≈ 0.7 inch) vertical accuracy. Diagonal = 2.3 cm (≈ 0.9 inch) (from center-to-center of the hits). Tested distance was 25m. The details of test can be seen below shooter's description.

Scope: Hawke 3-9x40. Air rifle is 2 months old. Indoor shooting (only last 3 meters were outside). I am not too happy with accuracy at 25 meters. Maybe I can't handle the recoil, but this accuracy is not enough for HFT. Video of this test can be found on Youtube at "airgun accuracy" channel.
