    I recorded the show (Aired on 7/13) and recompressed it small enough to be downloadable. I took away everything except them testing THAT myth, this is not the whole show. It is about 18 min of video. Quality is OK and I hope you enjoy.

    Anyone who would like to donate to help with the cost of bandwith can donate to my PayPal at benjaminaw@lycos.com
    (Yes I know they are Anti, it's what I have. :( )

    Admins, if this is not OK, just message me and I will take the video down.

    I'd rather watch the toaster as it darkens bread.

    Toasters don't darken bread, they make it heavy.

    Hey, thanks for taking the time to record that episode. I missed it being in the hospital, now I saw it.

    Anyone care to explain why the 3' of water stopped the faster rounds? Love the shotty slug though...what a riot.

    Heavy.

    Cause when it's done, it's no longer "light". :neener:

    I think only the faster rounds fragment while the slower moving rounds keep its shape.

    I think when you break the 2500 ft/sec mark, bullets just disintegrate on impact basically.

    If you noticed, the 9mm entered the water much more cleanly entering straight down. The 50 cal made a HUGE splash, throwing many gallons of water many feet into the air. Thats energy taken away from the bullet. I'll have to admit, I was very surprised with the results.

    My computer would take forever to download that. Would anyone care to summarize their findings?

    Thanks for taking the time to post that. That was good to watch.

    Funny how they were surprised about .223. It did what it was designed to do by disinigrating like it did.

    When I was a sprout, and still quite stupid, I got the bright idea to shoot a .22 LR into a full 5-gallon bucket of water, in the bathtub. Yes, I know... I was an idiot. Anyhoo, I learned that a 5-gallon bucket of water creates enough resistance that the bullet won't penetrate the heavy plastic of the bottom. I consider myself extremely lucky that it didn't ricochet up into me, or that it didn't drill a hole in the tub bottom. Boy, my Dad would have been hot under the collar if his tub got plugged!

    Crosshair could you give me some details about your computer setup that you used to record the show? I've been meaning to put together something similar.

    I was most surprised at how little the .50 BMG recoiled. I guess the giant muzzle brake had something to do with it. Their ads must be true...

    It's not much really. It is an AOpen DX34R-U Dual CPU mothroboard with dual Intel Confidential P3 Tualatin with 512Kb L2 CPU's running at 930 Mhz (143x6.5). (Don't ask me where (Or how) I got them, all I will say that the sale involved a subpoena from Intel. :uhoh: ) Then I have 512Mb of PC150 SDRAM for main memory. For graphics I have a RADION 9000 All-In-Wonder. I have a 120 GB Western Digital 7200 RPM 8MB cache har drive partitioned into two 20GB and one 80GB partition (OS, Programs, and Data). I use iuVCR to capture the video using MPEG-4 (NOT Divix, that pile of crap can burn in :evil: ) for video and MP3 for the audio. I use best quality when capturing, I shrink it down in post processing. (I use VirtualDub for that) I use the RCA-In to the AIW and run the cable connection through my Sony VCR. The VCR has a better tuner so I get a better picture. (Though I have to manualy change the channels.) I have a 100Mbit Network card to connect to my other two computers. (Yes I have 3 computers not counting my laptop. :D ) I have been toying with firewire networking lately though. My server stores all my video before I burn it to DVD for archiving. My server has 1.2 TB of storage space. I use a KVM to use all 3 from the same monitor. Here is a pic of my setup.

    Crosshair's Computer Setup - BIG FILE

    My video capture system is on the far right, my server is the one burried in the back with the rats nest of wires, and finaly, my "Everything else/gaming" machine is on the far right with no cover on it. My three VCR's are on the far right and my DVD cases are on the shelf below. Yes it is a bit of a mess, but I keep it sanitary. As you can plainly see, my computer desk is often my gun desk. The white noise of all of them running makes falling asleep easy. Yes, this whole thing is in my beedroom. :what:

    Some of the splash was also caused by the exiting muzzle gases. The barrel was only a few feet from the water. I bet if that giant brake wasn't on and no gases were diverted rearward, the splash would be much more impressive.

    What was curious is that he called the .50 caliber (didn't say BMJ) an armor piercing round. They used what appeared to be match rounds with no colored tip markings. They never told us if they are firing FMJ, JHP out of the pistol. They never said what ammo the M1 Garand uses (don't assume the audience knows). I felt it was a bit dangerous on the vertical tank to teeter up there with a 12ga. At least they tried to do an objective test; the main purpose of their show is entertainment afterall. At least it is better than an anti-gun piece.

    Oh, one thing of note. Did anyone else scratch their head when whats-his-name collected all the debris of the .223? It looked like there was more material than there should be in a .223 bullet.

    Thanks for the entertainment... What I am curious to know about, is in the movie saving private ryan, the rounds were going really far into the water, and hitting people. I can't imagine thoes rounds that were being fired (out of machine guns) were more powerfull then the .50 rifle, so in real life they wouldn't have been hit?

    I noticed the same thing. A .223 is what... half a cubic centimeter? It looked like he had a big fistful of lead. I've melted the lead out of soft-point 7.62x39 (Don't worry, pulled it out of the case first.), and I don't recall getting anywhere near that much material.

    Ok, upon further review... I think these guys are idiots now. Well, ok, maybe not total idiots, but out of their league here. I'm pretty sure the bullet is intact. At what my player says is the 12 minute mark, you can clearly see a bullet-shaped copper thing in the top right corner of his hand. What he calls "the very tip of it" looks just like the whole FMJ rounds I've seen in the reloading aisle of the gun shop. The rest of that pile of debris is WAY too much lead for a .223. Maybe the fragments from that muzzle loader shot that they couldn't find? He might have hit his test rig and caused it to fragment. There also may well have been shots that we didn't see.

    Ok, even further review... The flashback to the bulletproof glass thing talks about how the M1 punched through the glass. I didn't actually see an M1 in that shot. I did see what looked like an '03. Same round and all, but DIFFERENT GUN!!!

    Ok, forget it. These guys are full of it.

    There is a gelatin test using shotgun slugs which showed the same thing. The low-velocity rounds had better penetration that the high velocity rounds. Now if only i could find the link for that...

    They probably shot several times into the water. Then spliced it together to make it look like one shot. Notice when he is counting down to firing the 50 BMG on the shot looking straight at him the bolt handel is up. Obviously some splicing going on.

    Read way back about Army tests where they found 2500fps was the optimum velocity for minimizing deflection. Interesting that was the claimed velocity for the 223.

    That video makes me want one of those Marine Magnum 12ga even more now than I did before :) Funny stuff!

    My connection is very fast but if you dialin users rightclick and "save as" to your desktop things should go a lot quicker. Mine downloaded in the blink of an eye and I was watching the video in a few seconds.

    I got into an argument with a guy at work about that show. He claimed that they claimed that the 50 BMG was an AP round.....NO WAY!!! If it wasn't black tipped, it wasn't AP and if it was (what I suspect) a FMJ lead core, how does that differ from the 5.56 and .30? Of COURSE it would disintegrate hitting the water.

    Years ago, I saw a training film about UDT guys in WW11. They were free diving in a logoon into which a twin-50 mount was shooting and they had to swim out and fetch a couple of rounds as they sank. IIRC, they were zipping at LEAST 10 ft deep at about a 40 degree angle so they were penetrating 15+ feet of water.

    Thin jacketed lead core ANYTHING will perform the same on water at the same velocity. What were these goofballs trying to prove?

    It is always good to find another person who is part of the mainstream media that is a gun guy, which this Jamie guy apparently is. "Eyes and ears, everybody!"

    Don't nitpick, these guys are about the only ones in the "media" with a positive firearms attitude.
