I think "The Coach" should hang up his hat. This is the most egregious statement:

WARNING: DO NOT use 62 grain, green tipped, projectile ammo in the thinner barreled, bottom barrel in the photo, AR-15/M-4 rifles. Only use the green tipped ammo in the heavier barreled AR-15/M-4s. You will save yourself a lot of problems and a possible trip to the emergency room. :eek:

He doesn't even give any plausible reason. I've shot 62gr out of an M-16 and the only problem was poor stabilization.

I think I will skip parts 2 and 3...

Hello...I am posting from the intensive care ward...I shot 75g ammo out of my DD 14.5" LW barrel! :eek:


:neener:

No clue what he is talking about. 62g isn't very accurate in a 1:12 twist A1 barrel, but it isn't dangerous.
 
Proof positive that you can't believe everything (or most things) you read on the internet.
 
He answered my comment that he has some data/reference materials he will dig up and post in in part 2. I am truly curious what supporting info he has on the issue as I fail to see from a pressure perspective how it would matter?
 
He says below in the comments that the pressure will be higher and blow the barrel.

Of course he is wrong about it being higher pressure...they could load 45 grain ammo too hot.

If the barrel blew shooting in spec ammo..it has nothing to do with being a light weight barrel and everything to do with being a poorly made barrel.
 
Reckon this was posted after the failed ban on 162 ap? If you can't legislate it out of existence, then propaganda it out of existence.
What did P T Barnum once say-------
 
Pssssst. Fishbed

This site as well as many others offer far more accurate info than most of what's on your boob tube.
 
Why are we even discussing this article? It's poorly written and full of half facts and errors
 
Someone posted it on another forum as informational. It got plenty of "thanks" and very few rebuttals (save mine).

"The Coach" sounds suspiciously like a 14 year old shut on recycling Wikipedia info he accessed using his mom's wi-fi from the basement.

"Never use the forward assist" . . . so hasn't even been trained to do a deliberate load with a press check to make sure a round is in the chamber.

"Lots of problems with 62 grain ammo in thin barrels" . . . why yes, there are certain very significant problems with M855 through M16A1 barrels (but obviously not all light profile barrels), but this guy's info is so far off base that, really, this has to be some teen or tween trying to sound important with zero practical shooting experience involving the gun he's pontificating on.

Anyone want to take odds on part 2 or 3 advising readers they need to download all their mags to 28 or 18 rounds and that if your magazine rests on the ground while shooting in the prone the weapon will jam?

He doesn't even give any plausible reason. I've shot 62gr out of an M-16 and the only problem was poor stabilization.

It's a big problem, but definitely it's the only problem. M855 is authorized for emergency wartime use in M16A1s with the note that it's only suitable for use inside 100 meters due to the degraded accuracy. Pretty sure if there were any risk of blowing the gun all to hell the army ammo notice would be more along the lines of "thou shalt never shooteth the tips of green through the M16A1 that begat the M16A2, so help you God."

When he was discussing the down side of the FA, the first thing in my mind was a brass check, and to use the FA to ensure the bolt was fully seated. The rest of it, while not untrue, was not included as SOP in military doctrinal training on the M-16. Those are examples of how NOT to use the forward assist, specified in the manual. I'll see if I can locate mine and post this to back up my statement.
 
Like youtube, blogs allow those who need lots of public attention to get it - and it's not always a positive experience.

"If you don't like what I write don't read it!" isn't going to fly. Far too many others with a better grasp of the material will be more than happy to provide links to better answers. :D

Another superficial view of the M16 and quite shallow in it's research and understanding.
 
I was trying to reserve judgement and wait on his sources as there may have been something going on with A1 barrels and higher pressure in the 80s, but there would have to be some other contributing factor not in evidence yet. He didn't produce anything on that, just expected issues with higher pressures cracking bolt lugs, cam pins and high port erosion with higher pressure M855A1 loads in short barrels. All expected.

I can't imagine a bulged or split lightweight barrel scenario that doesn't involve catastrophic failure of the bolt lugs or worse. In that case, a heavy barrel may not bulge/crack, but the bolt lugs will still be gone...

Wouldn't know. I stopped watching it long ago.
 
More support for why I tend to ignore "preppers" and "survivalists"...

...when it comes to firearms info.

Most of them are preppers and survivalists first and knowledgable about firearms waaaaay down the list.

They tend to present as effective lint traps for all the mythology, innuendo, misinformation, legend, lore, wive's tales and misinterpretations out there regarding firearms.

I used to have an M16A1 clone I built using a GA surplus Colt upper and barrel with skinny profile 1 in 12 barrel...
No problem shooting green tip.

No accuracy issues? I saw a unit trying to zero on the range with A1s and green tip (apparently the guy ordering their ammo was not very good at his job). From the targets I saw, group sizes were consistently bigger than dinner plate sized at 25 meters, with occasional keyholing. (It was an NG armor unit on the range, and being tankers might have explained the minute-of-barn group sizes, but the keyholing suggested it wasn't just operator headspace and timing.)
 
What a idiot. What little he knows he doesn't understand and gives the wrong information for. That bit about ammo blowing up barrels is a total pile of BS. I agree with Tirod and Apache.
