Absurd statement on gun forums that make you laugh?

[cyclesarge]

it's not exactly a myth that m16 bullets tumble. it's just an over-simplification.

all spitzer bullets have significantly heavier rear ends than noses. rifled spin keeps the nose in front of the butt during aerial flight.. for loadings like the 5.56, generally between 250,000 and 300,000 rpm, IIRC... once the bullet impacts flesh, friction immediately destabilizes spin, and with some loads, causes the heavier butt end of the spitzer bullet to swing forward of the nose. it seems to be that this usually results in a large J-shaped wound, where the bullet "yaws" in the flesh. ideally, the load also fragments while yawing- jacket separating from the core and fragmenting further still. all of this can be lessened or exaggerated, depending on what the round strikes inside the body- different parts of the body have different densities. whatever the case... yaw, frag, or tumble.. this creates a significantly larger temporary cavity, as the load splashes into fluid-like flesh, as well as a nastier permanent cavity... either way, it creates a larger, bloodier wound than a round which sails through clean.

it's extremely variable-dependent. sometimes they tumble, sometimes they yaw, sometimes they fragment, sometimes they do all three.. and every once in a while they even just zip through cleanly and exit through a hole not much larger than the entry.

This is what I always thought people were talking about when they said 5.56 "tumbles". In combat medic school, they told us, if there is an entry would, don't ASSUME the exit wound is opposite the entry, since bullets particularly 5.56 can tumble , once they enter the body.

5.45....now that round tumbles!

wait.... the "myth of the tumbling m16 bullet" is that it tumbles through the air? i haven't heard that one... not sure why anyone would believe such a ridiculous thing. that's called "keyholing," and generally only happens to rounds coming out of severely shot-out or otherwise damaged barrels- NEVER by design.

that sounds like somebody misunderstanding another somebody's over-simplification of the 5.56's terminal ballistics.

Fouled riflings can fail to spin up a slug and cause it to keyhole.

I have a fast-twist .22LR (1:9") that's specifically intended to stabilize the 60gr. Aguila round, which will keyhole out past 50 yds. from conventional (1:16") twist barrels.

The general rule is the longer the slug, the faster the twist needed to stabilize it in flight, and the more likely it is to tumble on impact.

Dammed straight!

Only blued and walnut guns have personality/soul.
Guns don't have personalities or souls. Your gorgeous blue/walnut 1911 is no less or more effective than a Glock, just lower capacity. It may be prettier and mean more to you, but so what.

"Obama is a socialist/communist."

Cheeze, he's from HARVARD LAW SCHOOL! And he has spent the last two years desperately trying to keep the big Wall Street banks and the Big Three automakers from going out of business. Even his big health care reform protects the income of the filthy rich drug manufacturers and health insurance companies. If he was a socialist he would not be risking his career protecting fat-cat capitalists!..............................elsullo

I have this LNIB "Blah, Blah, Blah" very low round count, and I am only asking full retail price.

Seriously, do you honestly think that is going to work?

How 'bout the "I'll give you $400 CASH today" on the "$500 firm, "for sale only" gun"? Like everyone else is offering a different form of currency for the item that is FOR SALE ONLY!, or others are offering $500 in equal payments of $25 over the next 10 months. Do they really think you're gonna be so overwhelmed that they were able to come up with the princely sum of $400 all logic flies out the window?

Actually some people do want guns that there is no record of who it was sold to in a private party sale.

That's why they are sometimes called a "poison" round, they really tear up flesh.

That's one I've see quite a bit as well. While it's true that some people want a gun that doesn't have a "record", almost EVERY used gun that is selling for a USED price, doesn't have a record. What makes the one priced like a new gun different? Are they willing to sell to a felon? Willing to forge a -bill of sale- saying they sold it to someone else? I can't think of ANY used gun I've bought that would be any more or less trackable than any gun that has been posted at a NEW price.

So you're saying that the ding dongs advertising used guns at full new retail prices or higher are only marketing to the paranoid? Maybe we should request that NWFA add a category to the classifieds "WTS/WTT OVERPRICED AND UNTRACEABLE".

Op ask a simple question that could be answered by google in 30 seconds


14 replies so far and still has not got a answer to the question he asked , just guys telling him to do it himself,
run it like it is , pics showing feed ramps, references to out of state gun smiths, engine builders and cylinder head porters but not one portland area gunsmith which again the OP could just google
