Oh boy, grouse hunting season is soon starting here in Finland! And after moving into the middle of forrest, I have finally had a possibility to seriously tune my Winchester 9422m 22WMR rifle. I think my 9422m had some manufacturing problems or the previous owner broke it, since it gave awful groups even with the original iron sights or scope attached to it. However, I have used it in tight thickets to hunt hazel grouses in small distances, so I have dealt with it somehow. Anyhow, some time ago, I first lowered the iron sights so that I don’t need to consider the aiming height during the quick hunting scenarios. Furthermore, the front sight do not cover close targets anymore. The graph in the previously mentioned post is exaggerated a lot btw, at least the CCI Maxi-Mag .22 magnums do not drop that much even in 60 meters as you will see soon. Then I added the metallic ears to protect the DIY front sight. Recently, I also added a cover for the rear sight also tuned further a few days ago. Even a little scratch can wipe soot or paint away from the sights, and a small glare from the exposed metal can change the aiming figure too much in longer distances. Now the rear sight is also protected from most of the direct light and physical impacts, while the view is still enough open to read the field quickly. Then I took a round brass screw, coarse and fine grinding pastes, drill, and made a new crown for the bore. After ensuring that the bullets leave the barrel smoothly, I blued the grinding. Finally, I ground the front wood and the barrel bands so that they do not touch and bend the expanding barrel after shot hot. The floating of the barrel might also help the whole gun to vibrate naturally, but I cannot confirm that effect. Oh yeah, and of course I ensured that all the screws are tight. Now, instead of watermelon sized groups at 60 meters, my 9422m Winchester shoots all the bullets, from different distances without changing the aiming spot at all, in an area coverable by fist! Now, if I manage to spot a black grouse or capercaillie in an open field, I can shoot them also with more certainty! And I don’t hopefully need to soot the sights so often anymore, like shown in this video ðŸ™‚ Oh, and I needed to get my Winchester 9422m to function well specially with the CCI Maxi-Mag .22 WMR, because Finnish hunting law requires that a 2,5g bullet or heavier needs to exceed the energy of 200 Joules @ 100m, if one wants to hunt black grouses or capercaillies.
