ok guys. I am looking for a target that I can use on a 25 yard range to get a 100 yard bzo for my patrol rifle. A buddy of mine gave me a few targets that accomplished this a few years back but now I can't find them anywhere now. As I recall they looked similar to the military 30/300 yard(meter) bzo target but with a different horizontal line to aid in elevation aiming.

Anyways, some kind of target I can print from my computer (meaning it has to fit on a standard sheet of paper) would be helpful.


thanks in advance.

You are best if you can get a longer range. However from memory (which is risky) you need to around an inch low to be a little bit high at 100 yards.
If I was you, would probably set the sights an inch high at 100 yards - just as good as dead on for close and gives you the option for a little farther.

Thus one option is get a small black dot that appears to be the width of your front sight at 25 yards.
Use this for an aiming point at 6'oclock (i.e. the dot floats just on front of the front sight.
Adjust you sights so the group center is perfect for windage and about an inch low.
WARNING - from memory, need to check notes and/or a ballistics program.

I have used this set up and works fine for me. I site my gun in to hit 1" to 1 1/4" low at 50 yards. seems to be right on at 100 yards.

Makes sense to me. I use the 200m zero.
I zero at 50, impacting about 1.3 - 1.5" high at 100.
