Improved AR15A2/A3/A4 & AR15 Carbine Zero Targets - 50/200M, 100M, & 300M Zeroes

**thecolter** · 12-22-11, 08:06

I have created a series improved 25M zero targets (based of the standard US Military 25M zero target) that will allow the shooter to zero for 50/200M, 100M, and 300M using a 25yd/M range. The diferent targets are calibrated for both 20" full length service rifles and also 14.5" / 16" carbines with the shorter sight radius. The bold centering lines should assist in aquiring the good sight picture required for zeroing. These are also in different colors in addition to the traditional black for your individual preference.

Trajectories used were an average of M193 and M855 ballistic data. This should get most shooters in the right area. As you know, this can change with different loads.

All targets are designed for standard 8.5"x11" paper. Make sure your page scaling is set to 'NONE' in your print settings for proper scaling.

Grid dimensions for targets are:
Rifle Targets: .96cm
Carbine Targets: 1.3cm

Be safe and good shooting!

Also check out these targets created primarily for use with Aimpoint style red dot / non-magnified optics. There is a 50 yard zero target and adjusted 25 yard target with zeros for 50/200M & 100M.

Right on thanks for the effort. You way you used an average of M855 and M193 data. Would you mind providing the actual data you used?

I used Shooter, which is a ballistics program for the android OS to determine the different POIs at 25M. It's very accurate and I've used it with good success with my precision .308 at ranges out to 800 yards.

The following velocities were used:

20" M193: 3240 fps
20" M855: 3120 fps
16" M193: 3075 fps
16" M855: 2975 fps

What I did was plugged in specs for both M193 and M855 and came up with the average POI at 25M for the intended zeroes (-1.5" for a 100M zero and -1.2" for a 50M zero). The ballistics are so close at the ranges we are talking about here that the averaged POI shift represented on the targets works well for both 20" and 16" rifles firing either M193 and M855.

I can attest that it is an accurate average. I can shoot center mass on the 25m zero targets, then transition to a 100y/100m range and group center mass with both my 20" rifle and 16" carbine. The same goes with a 50m zero.

The dimensions for the 300m target are the exact same as the US Military target. The only difference being the colors and the bold lines.

Thanks for reposting, great targets and I like the consideration of colors. As someone who has a terrible time seeing the targets this is a big help.

Thanks for the good info and the time spent sharing these.

Wow could have used these yesterday when I was zeroing my irons. Any recommended type of paper to use when I print them?

How important is it to have the center of the target at the same height from the ground as the rifle bore?

Not really important at all at the range you're dealing with. That is unless you're shooting at some extreme angle, which probably wouldn't be safe in the first place.

Try to stay within a few feet of difference between the target height and rifle height from ground level and you'll be fine.
