M16A2 - M193 + M855 Ballistics Calculator/Chart?

[i3ond]

I am planing on helping my friend get ready for his rifle marksmanship qualification in the army.

I was wondering if anyone had information on ballistics with the round the army use's in qualification?

I plan to work with him on
* Breathing.
* Relaxing.
* Trigger Control.
* Proper Sight Picture.
* Front Sight Focus.
* Grip
* Natural Point of Aim.
* Prone and Kneeling Positions.
* Basic Adjusting for Windage.
* Basic bullet trajectory with a 25yd zero.
* Clearing Malfunctions
* Speed Reloading


If anyone has any suggestions let me know.

Thanks.

dont really need the ballistics of the round, the Army qual is about as easy of a qual as i have ever seen. But the topics that you got listed are all good and should get him right were he needs to be

With a 25 meter zero he will be zeroed for 300. He will have to hold at the base of the 50 and 100 meter pop-ups to achieve a solid hit,other than those 2 aim center mass. If he is a good shooter(36 or above) have him shoot at all his targets. If he is a poor shooter have him save his rounds from the 300 meter targets in case he misses an easy target up close. You can still shoot an expert with a 38 and never engage a 300 meter target. If he is a REALLY poor shot have him skip the 250s as well for the same reason. Save the rounds for a "Whoops!" up close.

He will be shooting M855,not M193.

Tell him to take his time,most targets are exposed for a bit before they drop. I watch most newbies and poor shots rush their rounds,not miss them due to not shooting fast enough.

Between targets tell him to lift his head off the stock to watch for the next targets,I have seen too many recruits engage one target and never fire at the other that popped up at the same time when the multiple target stages start.

With much respect to deadly0311 I think the Army course is a much better course to prepare for actual combat than the Marine KD course. Easier for sure but far more in line with the real conflict we are in.

you may think that, but there is 2 parts to the qual now, a KD out to 500m and then there is a combat shoot, 150 and in, movers, pop ups, and straight up close quarters shooting.

Wasn't aware of the new course,sounds like a much improved way to do things. I wish the Army would place the value on marksmanship the Marines always have. TJR

Army has a new part to its qual; it goes something like this but dont quote me exact.
Included is now 10 rounds prone unsupported and 10 rounds kneeling.

It's 20 rounds prone supported,10 prone unsupported and 10 kneeling. Targets from 50 meters to 300 meters,pop up and multiples included. TJR

so the army does the 25m zero with one click past 8/3. How would u make a ballistic chart with the odd zero?
M855
62g
velocity 3061 FPS
ballistic coefficient .304

Type your info into JBM if you really NEED a chart. But for qualification purposes I told you everything you need. The round doesn't have enough drop to miss an E type at any distance he will be shooting. A actual drop chart will confuse him more than it will help and will be close to impossible to hold with irons. Zero at 25 meters and hold center mass past 100,low at 50 and 100. It's not rocket science as 50 years of recruits who got 30s on the ASVAB have proven by qualifying. TJR

Thanks for clearing that up Trobertson, that is right on for the course of fire. And right on for nixing a ballistic chart at a qual. No way he is gonna need it. Your advice will get him qual'd.

Its probably a little late in the game as your friend has probably already qualified. Look around for a USMC range data book. Most of it will be useless unless you are firing a USMC course of fire, but the first few pages is packed full or ballistic info for the M16A2/A4. There are windage charts to tell you how to adjust your sights based on the wind speed, direction and distance to target.

Keep in mind that the Marine Corps uses a different zero. Our rear sight is modified to allow for a 200m zero. thats is why you will see the M16 @ 8/3 -2 on the rear elevation for zeroing. Army standards leaves it @ 8/3. So when reading the elevation portion of the manual, initial BZO is where the rear aperature is set. after that then it is all in the front sight post.

I would HIGHLY disagree with this as the USMC qualification course is for basic function and employment of the M16A2/A4 service rifle. the intention of qualifying with the rifle is simply being able to adjust for range and elev. at known distances and to effectively manipulate the functions of the rifle.
CQC and Combat live fire ranges are an abundance and especially the 2 in 29 Palms and in Pendleton. I've had Army units come to the USMC courses to train with us as well as Australian and British military. These ranges are designed for exactly that...COMBAT PREP...SO ...........( not bashing the ARMY) why ....would the ARMY units utilize our facilities @ March AFB and Victorville, Ca for Combat prep if the Army combat ranges were "more in line with the real conflict we are in"????


Respectively of course..................
