This morning i left the house just before eight, and there was zero breeze. What i wished to do was shoot the Omega at 400 yard. After driving 19 mile, and climbing about 1500' i came to where i could get 400 yard away from the target, but there was a breeze. It seemed it wouldn't be worth shooting in the wind, but it wasn't too bad, and i had come all this way. I really really wanted to shoot this rifle at 400 yard. The load was changed from 120g BH to 115g BH, and i thought i should probably try this new load at 100 yard, but i wanted to beat the breeze, so i skipped on to 400 yard.
I guessed the muzzle velocity at 2300 fps, and the program told me to raise the bullet 15 moa. This is what i did, and the first shot hit a way low and left. The second shot i couldn't see. The next 4 shots hit near the first one, and made a nice looking group. Then the targets started blowing off the cardboard, so i had to quit, and drive the 400 yard to save them paper. Tape was placed so to keep the paper from blowing off. Them 6 shot are shown in the following photo.
Note where the second shot went. Now, seeing where the bullets hit, i wanted to shoot more, even though there was a definite light wind that came and went. The elevation dial was turned 2 moa higher, and i went back out to 400 yard, and made 3 more shots. Them shots were awful. They are the 3 strung across the target area; 1 in the cardboard, 1 in the red, and 1 in the white.
It was disgusting, trying to shoot in the wind, so i quit, and moved a mile or so and set up at 100 yard. Here there was only a very slight breeze. The elevation dial was turned down 16 moa, and i shot 3 times. These shots are in the bull. These shots at 100 yard made it seem that the muzzle velocity is about 2250 fps. Using this bullet, and raising point of aim from zero at 100 yard by 16" is supposed to have these bullet zeroed at 400 yard. More shooting is required; hope the breeze cooperates soon.
