I thought the purpose behind M855 was better barrier penetration over M193 because the military was having problems with it not penetrating cover. I’ve also been told that it goes straight through soft targets leaving a .22 hole and doesn’t tumble. Correct me if I’m wrong, but I would assume M1/M2 ball would perform better? Maybe the point is like others have said, to encroach more and see what they can get by with or to drive sales of M855 or just run the prices up.February 16, 2015 at 8:59 pm #36664

A bullet from a rifle doesn’t need to tumble to create damage. Shoot a full soda can with a 22lr and see what happens, the can essentially explodes. The bullet entering the can creates pressurization of the liquid bursting the can. A high velocity bullet passing through wet tissue (human bodies are bags of water) pressurizes the surrounding tissue causing damage. Soft points and hollow points increase the effect transferring more of the bullet’s energy into the tissues.February 17, 2015 at 12:54 am #36668
I’ve read the max effective range of a 5.56 for it to fragment is about 200m. Beyond that … a hole. The energy isn’t there.February 17, 2015 at 1:55 am #36672
We beat the effectiveness of the 5.56 to death a while ago. Wikipedia has a good objective analysis from all points of view for anyone that is interested or hasn’t already come to their own conclusions.
For most people terminal performance is not the only criteria to use when picking a firearm and cartridge. If it was we would all have a 50bmg.February 17, 2015 at 2:16 am #36677
This is a link to a ballistic-chart for the 5.56×45February 17, 2015 at 2:38 am #36679
Great 74… Rick Grimes carries an AK. So will I when the shtf. lol
Do you have a reference to the thread you’re referring to?February 17, 2015 at 2:49 am #36681
I’m guessing it’s in here.
With your AK you still have a 200yrd gun.February 17, 2015 at 4:29 am #36684
With my eyes , I dont need more than that . AK for me as well .February 18, 2015 at 5:14 am #36747
I’ve been reading wikipedia and other articles(thanks for the link) and apparently there is much better stuff out there now. I assume the draw for most people with this is because it was the NATO standard for so long they produced tonnes of it there is a huge supply and until recently not too much demand ergo low prices. Is the newer stuff available on the market?February 18, 2015 at 6:54 am #36748
Newer? Most commercially avail 855 is new manufacture. Same for SS109.
Contract overruns, intentional or sccidental, as well as just making a wanted product.
As to better? What criteria for better?
Pretty much all HP and SP loads provide better terminal ballistics than any ball round.
And assuming a compatible barrel twist, better accuracy.February 18, 2015 at 11:31 am #36757
I’m don’t know if anyone looked at the balistics chart, but the 5.56 at 750 yards, has about the same energy as a 22lr has at the muzzle.February 18, 2015 at 2:07 pm #36764
