Went back to the range yesterday and shot at grouse-head sized targets at 50 yards.
Standing position: took forever to get enough stability to even shoot - quite challenging and not realistic. Not sure if practice could really accomplish a grouse head sized accuracy from standing position.. Possible, but really difficult. 0/5, two of them were grazes.
Kneeling: More stability, but still shaky enough not to make it any more useful than standing for a grouse head. Again, possible, but I wouldn't choose this. 1/5, but the one that hit almost classified as a graze.
Sitting: Much better because many muscle groups are removed from that equation. In theory. I got 2 out of 5, but again, one was a beak shot, the other was at the edge of the neck. Note, I took a long time posturing and re-posturing and breathing and setting into the stance here.
Prone: This is more of a 3/5 solid hits. Much more stable and the missed shots were more like grazes.
Prone with bipod: 5/5. Almost all in the eye except for one. I must say that even though I did get 5/5 -> I took a good 30 seconds to set up. A moving target would be very difficult.
Then I went to the 25 yard range.. Story was MUCH different here, working with half the magnification (x4). Headshot from standing is much more possible, but still challenging. No real need for prone, but if the bird isn't moving then I guess there is time for it.. I'd say a calculated standing shot with an adjusted rifle sling would be sufficient. But I would probably kneel at this point, or find a tree to lean on and stabilize.
10-15 yards was perfect for standing. At 3x magnification was probably a bit too much - 1-1.5x would have been plenty - or a red dot.
Lesson learned: way harder than I remembered lol..
