24 Hour Sniper Adventure Challenge
Mudinyeri:
Training continued yesterday afternoon. It was a perfect day to head down to ENGC for a little shooting. Neither Nick nor I had ever shot out to 600 yards before, even though I put together a gun to do it over a year ago.
We started out at 100 yards. I put three rounds through my bolt gun, two of them touching and 2" high, windage was about 1/4" right. I made a slight adjustment and put a round in the same vertical plane 1" high - just where I want to be at 100 yards.
We ran a few rounds through Nick's AR with an EOTech and then moved up to the 600 yard range.
With my rifle zeroed for 200 yards, it took me six rounds to get on paper (man-sized target). The next ten rounds are shown below. I walked the shots in from the right side of the target toward the bull's eye as I adjusted for wind (coming from about my 11:00).
With windage and elevation pretty well adjusted, Nick put four out of four rounds on target.
For the seasoned long range shooters, a couple questions:
1. I zeroed my rifle 1" high at 100 yards in the prone position but was shooting off of the tables at ENGC yesterday. Would the different position account for the additional 1" elevation difference that I saw in my first two 100 yard shots yesterday?
2. Is there any place around the Omaha area where we could shoot out to 1200 yards?

Switching from prone to the bench would cause some shift, but I doubt if it would cause a full MOA.
What bullets and load are you using? 1200 yards is going to be quite a stretch for a 308. You might want to consider a Lapua Scenar. They're expensive, but they have the high BC of a heavy bullet and they're light so you can push them to higher velocities.

Bullet is Hornady A-Max 178 grain. Load is a "secret" worked up by a buddy of mind from Californiastan who is an ammo manufacturer. The load is specific to my gun and the bullet and the ranges that I wanted to shoot. He also told me that 1200 yards would be a stretch but that's the absolute maximum that I would have to shoot in this competition. I need a blend of a relatively lightweight rifle and ammunition (have to carry 50 rounds) as well as an ability to potentially reach out to 1200 yards. We'll be covering 30+ miles on foot while carrying our full load-out, including rifle, sidearm and ammo for both.

The 178 Amax is supposed to do a good job transitioning to subsonic.

Do you mean over the course of the bullet's flight or by changing the load to slow the bullet's speed initially?
