I have often heard it said, "recoiling spring piston airguns simply can not be shot (accurately) from a bipod or a solid rest". I disagree.
Granted, it is generally much easier to get good groups from a recoiling springer when a soft pillow, or similar rest is used, but a solid rest can also be used with good results. It is primarily a matter of the shooter adapting to the firing cycle of the gun. Obviously, the harsher the firing characteristics of the gun, the more difficult the shooter's job becomes.
I finally had a chance today, to do some proper testing with my HW97K and my home-made bipod, detailed above in this thread. The HW97K is shooting right on at 12 FPE, and has a very smooth firing cycle. The first few shots indicated that the POI from the bipod, as opposed to the POI when shot with elbows rested on knees while seated, was about 2" high, but dead center. Once the scope elevation was adjusted for around a 20 yard zero, I did some testing for grouping while shooting from the bipod, and the attached pic shows groups shot at 10, 15, 20, and 25 yards. I'll be doing further testing, out to 55 yards when time permits. The 15 yd group was shaping up to be the best of the bunch, with the first four shots in about a 1/4" dia ragged hole, and then I pulled the last shot, labelled "me" - LOL! Not too shabby, considering lightly gusting wind thrown into the mix. When shooting offhand now, an estimated 2" of "hold-under" must be used.
