Shooting the Gong
That's the gong set-up. Shooting was done from the top of hill where the trail/road crests. Range was about 295 yard. The first shot was a miss a touch high, and into the wind.
Here is a video of the miss.
The wind meter read between 4 and 8 mi/hr from the right, so the windage was twisted 2 1/2 moa into the wind. The elevation dial was twisted up 8 moa. After the first shot hit some high, and right, the elevation dial was twisted down to 7 moa, and the windage dial was turned to 1 1/2 moa right. The second shot was a hit.
Here is the video of the first hit.
Here is the video of the second hit made by the third shot. And that was that, it was time for lunch.
The two photo show where the 3 shots taken today hit. One on the ground behind, above, and right of the gong. The next two hit pretty close to each other on the gong.
Rifle was a 45 caliber Omega. Load was 200g Shockwave, 115g Blackhorn, baby blue Harvester sabot, W209 primer. Scope settings were determined by the following calculation which was close, but not exact.
After seeing that the first shot hit high, i figured it was because of the angle. So, i turned on the gps, and read the elevation where i shot from as 5050', and the elevation at the gong was 4920'. When i got home i calculated the angle to be 8.45 degree, and did the ballistic calculation again.
Hmm, not much difference at all, the reason for the first miss was not because of the downhill shot it seems

575 yard
Today the gong was placed near the same place as yesterday; just a little to the side so to avoid yesterday's bullet marks. The bench was placed on the next further hill; brain figured it was a 475 to 500 yard shot. However, brain was incorrect. The elevation dial was set for a 500 yard shot. The windage dial was set for a 5 mph wind for a 500 yard shot. The laser say it was a 575 yard shot.
The dirt splash above the pipe in the photo is the bullet hitting. It is too low, and too far downwind. The shooter can barely be seen on the ridge top just to the right of the truck. The elevation dial was twisted up some, and the second miss was made.
Here is a VIDEO mostly provided to hear the sound of the shot echo. The elevation dial was turned up more, and the third miss was made. Note how the bullet skipped. The echo of the shot sounds good to me.
Note how the next miss is almost blown into the support leg; the reason for a long pipe. The wind kept changing from about 4 mph to 11 mph. Direction was from the front left.
Here is a VIDEO of the last shot. The last vial of powder it was.
That the gong was hit in the center, and it only rose up a fraction of what it did, when hit from 300 yard, sure shows how much energy the bullet looses when it flies from 300 to 575 yard.
