M855A1 Ballistic Gel Test

what's up everybody welcome back to the wind channel so I hope you're as excited as I am for this test I'm finally going to do m855a1 you can see sometimes known as brown tip this is a 62 grain lead-free EPR round so enhanced performance round so this is the Army's replacement for green tip and we're going to shoot it into a block of clear ballistics gel nothing nothing better than a fresh block because you can see what an old block looks like that's from the 6-8 spc tests so I've got my 16 inch barrel ar-15 chronograph and a round of m855a1 I'm going to send it down into the ballistics gel and see what we get m855a1 out of a 16 inch barrel versus clear below start here with the velocity 29 82 pretty good for a 62 grain round out of a 16 inch barrel and I actually flipped the gel block over so you guys could see this a little bit better the shot came in really low you can see this is now upside down the shot came in there and and the neck on this round is unbelievably short I mean this it's one of the things they were trying to fix from the green tip round you know the m855 had a lot longer neck and what that leads to is if you shoot a skinny person with it it may not tumble or or flip over or try and fragment until after it leaves their body so really then you just get these little ice pick 22 caliber wounds and that's not really what the five five six round that's not its primary wounding mechanism you know needs to fragment and shed all that energy and kind of tear everything up so you can see that the neck on this round is almost you almost can't measure it I mean right away it's starting to turn and it's and it flips over I mean what is that like a half inch you know it's a it's a tremendously short neck and a lot of damage there up front and then you've got a pretty decent permanent wound channel that comes down I think it's a little bit uh it doesn't look as big as it would if I shot it in the center of the block because right here you can see that the pieces of it came out so that's cut right there so you got this huge gash right there and I'm sure you can see down through the bottom see through the bottom of the gel there's a big hole in the box so yeah we we came in a little low and and some of the some of the bullet fragments came out of the bottom of the gel or else this all would look bigger but moving on down you can see that that steel penetrator all the way through the gel block I'm not sure if you're going to be able to see it in this one see that little line right there went all the way through this block to about I'm gonna have to cut it out of there but it's somewhere right around here so you know you're looking at so 24 22 24 inches of penetration so devastating fragmentation up front and still a lot of penetration from the steel piece and that also comes from the fact that that steel piece is really meant to assist with going through barriers glass steal stuff like that so let me cut that little penetrator out of the cruddy jail block and we'll take a look at it what's pretty interesting is that the part that I found that went 20 some inches into the other gel block is not the steel penetrator it's actually the copper slug that's behind the steel penetrator which is pretty neat and what it tells me is that that one of these holes in the bottom is probably from the steel piece that came out you can get a better view of the steel pendant or the copper slug there so my my best guess as to what's actually happening here is the brown goes in starts to yaw immediately the steel part rips its way out of that jacket shattering the jacket that's why you see all those little copper fragment pieces all over I believe those are pieces of the jacket the steel penetrator very likely deviates you know pretty radically from the original wound channel that's probably what came out of the bottom a look at the move the box and look at the table but I'm guessing that that steel piece probably had no trouble going through a plastic table like this and then you bet that copper slug that kind of continues on and penetrates deep I think since I'm already here I'm going to go ahead and take one more shot and try and come in a little closer to the middle of the block and see if we can get a little bit better depiction of that damage if we Center it up in the block we got that shot a little bit closer to the center of the block and you can see just a just a tremendous amount of damage here up front again extremely extremely short neck tons of fragmentation tons of damage up front you got one piece that yacht over that way probably a large piece of jacket and we still have a pretty decent wound channel that comes all the way down exited the block went into this block and from what I can tell which it's right back here it looks like it went about 30 inches of penetration so let me get a knife and cut that piece out and find out exactly where it was okay there's the copper slug that I cut out of the second ballistics gel block and I went a little bit deeper than the first shot it went about 30 inches total went all the way through that block and it was it was right about here in the in the second one so yeah I would say that this is definitely an improvement over green tip looks like much more consistent and earlier fragmentation you still have the penetrator that drives really really deep 3,000 and 3 feet per second that time so a pretty good velocity pretty hot for a 62-grain round like I said that's out of a 16 inch barrel but anyway there it is m855a1 the EPR round ballistics gel test as always thank you guys for watching the wound Channel and we'll see you next time
