I always struggle in a cross wind shooting long distances like 100-200 yards with a pistol. This is because I usually rest the gun on the magazine base plate and leave the muzzle end free. This is great when one wants to learn to shoot the gun without moving the gun, but a cross wind can move the gun a little left or right. The movement is visible to the shooter as the dot jiggles around just enough to throw the shots off usually left or right while trying to line up the shot.
Today I improvised a front dust cover rest to use in addition to my usual wrist rest. The purpose was to provide a little resistance to lateral movement of the gun by adding a second point of contact. The weather conditions today were nearly identical to what I experienced on Wednesday, gusty cross winds from the 3-4 o'clock direction to the line of fire. I shot 20 rounds on the first target using my usual wrist rest support, and had some a little high and some to the right, just like Wednesday. For the second target, I improvised a rest just in front of my usual 4x4 plus rag support using a fat round rear squeeze bag for rifle shooting. No other changes. I could tell just from the view through the red dot that this was going to work well, as the dot settled to what I see on a calm day. The groups from target 2 were good but a little low right, but the experiment was going well.
For target 3, the only change was 1 up, 1 left on the Burris Fast Fire 3 to move the groups a little closer to the x ring. I think it took a few rounds for the sight to settle in, but the last 12 shots for the day were good except for one when I flinched slightly when the 30-06 two tables away went off just before me. So
11 of the last 12 shots were in a 4-1/2" group, albeit still a little low right. Here is the video of all 60 rounds, three targets.

The muzzle sank down too low in the bag and the muzzle blast shredded the canvas bag material. I'll use something different next trip out.
I still think that the best way to refine one's trigger control and finger tension is with the gun only supported at the magazine base plate and/or wrist rest. But, in windy conditions, that isn't enough, at least for my somewhat weak grip. Perhaps folks with vise grip strength won't see much improvement in a cross wind by adding the second contact point. And I didn't have the rear of the gun solidly on the block any longer, because I still had to have some freedom to line up the dot vertically, so the magazine base plate was floating with the dust cover on the bag.
Yes, I'm going to clean the barrel. I won't shoot the gun again for a while and it goes back in the safe after a bore clean and oil.
