The 6.8 appears to be the best answer, AR Magazine had a pretty good writeup this month. Captain Crunch in the 90's has converted a vast majority of our M14's into shavings. Expanding bullets, despite their effectiveness will never be an option. | |||

My son is in Iraq and I did an extensive study on the ballistics of the M855 “Green-Tip†ammo used by the Army so I could get him a set of BDC dials for his Leupold scope that he uses on his M4 and some ballistic range cards for him and his guys. M1 Tanker (AR member)was nice enough, as always, to send some of this stuff and I had it chronographed out both a short barreled M4 and an full length A2. The difference in velocity was actually pretty small...averaging around 100 fps. Unfortunately, Geneva Convention rules prohibit certain types of projectiles for rifles used in combat so the best possible “killers†are seldom used. The Marines have been having really good performance from the Black Hills 77 grain 5.56mm rounds they are using in Iraq. The military also has huge numbers of M14’s sitting around gathering dust and lots of those have been resurrected for use in both Afghanistan and Iraq. My son’s company has five designated marksmen who carry M14’s. Bullets don’t have to “expand†necessarily to be effective but they do allot better job when they create a larger temporary wound channel than the current M855 ammo does. It pretty much just punches a nice 5.56 mm in and out hole with very little disruption of the surrounding tissue since it was designed to punch through body armor that our current enemies don’t wear! Personally, I think that’s pretty damned rude of them. You may see a shift to the 6.8mm in the special ops units but don’t hold your breath on the regular forces getting it in our lifetime...too many politics in the military and the pentagon. | |||

I talked to my son in Iraq this morning and the Army is so afraid of “collateral damage†that they are talking about removing the M2’s from the Humvees for some units operating in the denser populated areas like downtown Baghdad. It’s getting so bad, PC wise, that you almost have to have a chit from God to call in supporting fire from either mortars or, heaven forbid, artillery or air if there is a civilian within a grid square of your target. | |||

Change the twist back to 1 in 14 so that the bullets are marginally stabilized. It was the tumbling bullets out of 1 in 14" twist rifles that gave the original M-16's such a fearful reputation. The Army went with a 1 in 12 twist because they found that the 1 in 14 would not give the required accuracy at long range (500 or 600 yards IIRC) under extreme Arctic cold. Well, since this is Iraq and extreme Arctic cold does not seem like it would be a problem, a simple twist change would add all the lethality one could want. Of course, they'll never do it, but since you askeed... Gunnery, gunnery, gunnery! Hit the target, all else is twaddle. | |||

I was in the Corps when we first got M16’s in 1967 and it was never the weapon itself that was the problem...it was the ammunition, specifically the type of powder used. Urban legends aside...Bullets from M16’s never “tumbled†in flight. Their high velocity and light weight (55 grains) caused them to “tumble†or break up once they hit something...but had they actually been “tumbling†in flight it would have pretty difficult to hit anything (on purpose) in the first place. In order for any bullet to be “lethal†it first has to strike the target in a vital zone...and that is very difficult to do, except at very short range, with a twist that does not stabilize the bullet in flight. | |||
|
one of us |
Of course you're right, the bullets do NOT tumble in flight. The 1 in 14 twist stabilizes the bullets in flight well enough, it's when they hit a suitable medium, like flesh and blood, that their marginal stability means the bullet is MORE LIKELY to tumble inside the body. A stable FMJ will just penetrate straight through with minimal terminal effect. That's what I meant by "tumbling bullets". Sorry I did not explain myself well. ---------------- I well remember the screw up with the powder. Stoner originally developed the 5.56mm ammo using IMR4198 or a reasonable facsimile thereof. Then when the round was adopted by the military they switched to a production grade of Winchester 748 ball powder with a higher calcium carbonate content (fuzzy memory about the calcium but I think that's right) which caused much more fouling of the gas tube. Gunnery, gunnery, gunnery! Hit the target, all else is twaddle. | |||

And what ammo do the designated marksmen use? I'll bet you it's JAG approved HP! They've determined some HP ammo doesn't violate the Hague Convention. Well, this same type of "accuracy" ammo could also be approved for the 5.56x45mm! Just my opinion. | |||

The military uses 7.62mm 175 grain M118 and M118LR FMJ match ammo for snipers and designated marksmen...and it does not have hollow point bullets. The BTHP bullets you find in commercial match ammunition was designed for bench rest shooting at paper targets...not hunting, so the hollow point obviously was not designed with wound ballistics in mind. From what I understand the hollow point is a by product of the process of forming the jacket to the core. | |||

Jim, Actually, the M4’s and A2’s use a 1-7 inch twist not a 1-12 inch. If you went to a 1-14 inch twist (or even a 1-12) and kept the M855 ammo you would be lucky to hit someone at a hundred yards...and it probably would start tumbling while in flight. The steel penetrator in the tip combined with the extra length of the boat tail makes a projectile that needs more spin to even marginally stabilize in flight. | |||

Road Apples! The M118LR carries a 175gr. Sierra MK Hollow Point.... It's predecessor, the M852, carried a 168gr. Sierra MK HOLLOW POINT. The standard M118 ball is a crappy 172 gr. BT-FMJ with exposed lead base! | |||
|

I won’t repond directly to certain obnoxious individuals but the Geneva convention defines HOLLOW POINT bullets as those that have a CAVITY designed to expand upon contact with human flesh. M118 SPECIAL BALL ammunition has no opening at all at the tip...and the M118LR and the M852 have, literally, a pin hole smaller than the point of a safety pin that is left after the jacketing process and which is not designed, nor does it function as an expanding bullet or a HOLLOW POINT as defined by the Geneva Convention. If someone wants to argue over a PIN HOLE I would suggest they go back to the Political Forum where their language and attitude is far more at home. | |||

Not the "Geneva Convention", Rick. That was the Hague Convention.
M118 Special Ball IS the M118LR and uses the 175 gr Sierra MK Boat Tail Jacketed Hollow Point. It's been blessed by the US Military legal folks as was the M852. I think that they could also improve on the M855 by giving it the "hollow point" treatment and still be "legal". Rick, I'm not trying to provoke an arguement. I'm just sticking to the facts. Sorry, if you took it wrong way. | |||

IIRC, both the boat tail and "hollow point" design features of the match bullets are intended to enhance the ballistic coefficient of the bullet. It is a "hollow point" because the base is totally enclosed in jacket material. This hollow point is not intended to, nor does it, expand in the fashion usually found with hunting type hollow points. I'm not familiar with the design of the M855 bullets, but IF they are a FMJ design with exposed lead at the base, they sure would NOT benefit from a "hollow point" drilled into the tip. JMHO, and worth every bit of what you paid for it! Regards, WE | |||

The M855 bullets do have the exposed lead base. I agree a hollow point with an exposed lead base would be BAD NEWS! What you would get is the lead core coming out of a copper tube! The Russian 5.45x39mm (7M6) round also has a steel penetrator like the M855. But it has a larger empty cavity in front ot the penetrator which causes it to destabilize rapidly when it strikes a target. The effectiveness of the Russian 7N6 military load, due to this tumbling design, earned it the nickname of the "Poison Bullet" from the Afghans who faced it in combat. | |||

The M855 is a better cartridge than the M-193. But there are still better designs. The problem is....... the cost! | |||

Seems like the poll is for 6.8 very intresting. I would have thought being into reloading and ballistics more of you would have been for ballistic tips or some other bullet. Guess thats what I get for assuming... | |||

How about looking at the Soviets 22 cal bullets and ammo they use, I think they have a "space" between the nose and where the lead starts, giving them a dramatic tumbling effect when contacting the target. If you go to a longer bullet (ie heavier wt) you will not have to change the twist of the barrel to get the desired effect. this longer bullet would allow for an air space in the nose to allow quicker destabilizing once contact wiht the target is made. | |||

I would so much like to talk about the "PC-ness" of ROE and the Laws of Land Warfare, but I cannot (legally) until I retire. Regardless, such situations as your son related do happen, and much, much worse. This particular topic was, and IS, my number-one gripe about the war in Iraq. I am very frustrated by the whole situation. Russ The doing of unpleasant deeds calls for people of an unpleasant nature. | |||

I would like to add this, regarding the Hague Convention. We are not bound by it in Iraq. We are facing insurgents, not an organized military representing a nation state. We can legally use hollow-point ammunition and any other damn thing. For legal reference on this, I invite you to read Hays Parks comments/findings on this matter. Since "the end of major hostilities" in Iraq in the Spring of 2003, we have not been bound by any imposition on the part of the Hague Convention. Regardless... the brass is restricting us. If you don't like it, and you'd like to see your sons and daughters have a little more punch, annoy the ca-ca out of your legislators, and don't let up.

Russell is correct about the legality of using softpoints...Its basically the same reason as why civilian Police can use softpoints, but soldiers in war can't. Morally in Iraq the situation is in limbo, so the brass play it safe so that the liberals and world opinion have one less thing to attack America on..We were caught up in the same way in NI. | |||

I know very little about the topic here but I have read that that MatchKing hollowpoints are approved for combat and if you search a little you can find legions of posts by hunters who hunt deer with MKs exclusively.

M118 Special Ball is NOT the same as M118 LR. The M118 SB uses a 172 gr BTFMJ bullet, NOT a 175 BTHP. The M118 LR uses the 175 BTHP. The M852 used the Sierra 168gr BTHP and is specificaly marked "NOT FOR COMBAT USE" on the ammo boxes. I have shot lots of all of the above. Some of it in combat and and in matches. I am not going to get into the legality argument of the whole thing here. But here is a link that will give you the specific data on the various loads. It is right out of the Army ammo TM. http://www.ar15.com/content/manuals/TM43-0001-27.pdf#search='army%20ammunition%20TM']Ammo%20Manual The M118 LR data can be found by searching the web.

This comes from the Special Operations Force Command, dated 1985, concerning “Match King†BTHP bullets in warfare. And I will correct myself by saying that it is the Hague Treaty, not the Geneva Convention that prohibits the use of “expanding bullets†for warfare. “Bullet Description. As previously described, the MatchKing is a boat tail, ogival spitzer tip bullet with open tip. The "open tip" is a shallow aperture (approximately the diameter of the wire in a standard size straight pin or paper clip) in the nose of the bullet. While sometimes described as a "hollow point," this is a mischaracterization in law of war terms. Generally a "hollow point" bullet is thought of in terms of its ability to expand on impact with soft tissue. Physical examination of the MatchKing "open tip" bullet reveals that its opening is extremely small in comparison to the aperture in comparable hollow point hunting bullets; for example, the 165-grain GameKing is a true hollow point boat tail bullet with an aperture substantially greater than the MatchKing, and skiving (serrations cut into the jacket) to insure expansion. In the MatchKing, the open tip is closed as much as possible to provide better aerodynamics, and contains no skiving. The lead core of the MatchKing bullet is entirely covered by the bullet jacket. While the GameKing bullet is designed to bring the ballistic advantages of a match bullet to long range hunting, the manufacturer expressly recommends against the use of the MatchKing for hunting game of any size because it does not have the expansion characteristics of a hunting bullet. The purpose of the small, shallow aperture in the MatchKing is to provide a bullet design offering maximum accuracy at very long ranges, rolling the jacket of the bullet around its core from base to tip; standard military bullets and other match bullets roll the jacket around its core from tip to base, leaving an exposed lead core at its base. Design purpose of the MatchKing was not to produce a bullet that would expand or flatten easily on impact with the human body, or otherwise cause wounds greater than those caused by standard military small arms ammunition.“ | |||

You are correct, the M118 Special Ball is NOT the same as the M118 LR. BUT..... the M852 was approved for sniper use before the introduction of the M118 LR.

In Viet Nam, we had the problem of the 5.56mm bullets being very undependable in triple-canopy jungle. This was solved by the use of 12-ga shotguns shooting buckshot...... As mentioned, the Geneva Conventions prohibit the use of certain kinds of ammo - one of these prohibited is the .50 BMG round (for use on people), and of course, expanding bullets. Yet, considering that those we are fighting in Iraq and Afghanistan are not protected by the Geneva Conventions, I see no LEGAL reason why these projectiles could not be used. However, their use would no doubt provoke an adverse reaction from those whose prediliction is to "sit on their ass and howl"....

Personally I think this is a situation of us trying to put the cart before the horse again. What the bad guy is hit with (bullet weight and caliber) is of much less importance than the hit itself. It makes no difference if an enemy is missed with a 5.56, 6.8, or 7.62, it makes a huge difference if he is hit period. Training in the US military has made a great deal of progress since WWII regarding rates of fire, but what is still lacking is hit percentages. We have come up with some very good concepts, ranges that support those concepts, and some gear that really helps, but the need is to be able to hit reliably at battle ranges under stress. The training to do this is simply non-standardized, and therefore not accomplished by all units, even those expected to serve under enemy fire. I can't speak for any of our other posters who've been to the latest 2-way rifle range, but for myself I can tell you I did not care one bit if a round fired at me came from an AK or RPK, or if a mortar round was 60mm or 82mm. Nor did I ever wish my rifle was of a different chambering, or that I had non-standard ammunition. My only concern was being able to fire on the enemy and maneuver against him. All I want is a reliable rifle and ammo combination and the training to use it that will save my life (which I had); everything else is simply mental masturbation.

Very true Gunny. And as a retired Marine I “understand†you perfectly! If all the nasty little projectiles flying around a battlefield made contact with a human being battles would be measured in seconds instead of hours, days, or weeks...and everyone on the field would have been hit at least once! | |||
