Testing the 5.56mm MK318 MOD 0 / 5.56 SOST ammo

The 5.56 SOST  is the ammo currently being used by the USMC and other troops in the GWOT,  it has not been available for the public to buy for very long so I, like a lot of other people have been curious about how it performs. The round was designed to  have better terminal performance and accuracy from short barreled rifles with a muzzle velocity of 2925 fps from the 14.5 inch M4 barrel.  The round is a OTM,  this is important to remember as it is not the same as a hollow point.  It does however, offer up better performance and is barrier blind. The bullet itself has a thick copper base and a lead front end with the usual open tip that results from the process of making the bullet.  Also present are the rings seen around the bullet much like a barnes triple shock X.  A lot of people assumed and still do that the SOST is a barnes solid copper TSX, but it is not.

After getting my hands on some of the ammo I decided to test it for accuracy first. Since the ammo is intended for combat weapons, I chose to use my Colt 6940  with milspec barrel with 1/7 twist. I did put a Leupold 18x target scope on the carbine though so i could get all the accuracy out of it I could.  I fired 2 strings of 5 shots at 1 inch dots and one string of 10 shots of M855 to compare it to the common military load all at 100 yards. It was around 1100 AM , sunny with a  2 oclock 18 MPH wind.

Other then the normal 1st round flyer you usually get from hand cycling the action as opposed to letting the recoil operate and chamber  the next few rounds, the ammo showed some  great potential. The group on the left  was a little worse due to my own bad trigger work and lost concentration on one shot, but still pretty good considering. Now I know some claim  5 shot groups tell nothing, but if you over lay to  strings you get a pretty good idea  and you keep barrel heat down and mirage off the barrel messing with the scope.

After shooting the groups I decided to test out how the round matched the trajectory of the M855 since that is one of the things the SOST round was meant to have in common with the green tip. Out to 300and 400 yards  the SOST did match the BDC of my TA31F  ACOG and zero of other scopes and Aimpoint RDS I had on hand zeroed for the green tip. Also when comparing the position of the groups in relation to the aiming points, you can see on paper that the zero held very close for both rounds.

Now, the real surprise for me, was how good the lot of M855 I shot turned out to be!  Many gun board expurts and gun magazine expurtitions will gladly tell you how terrible green tip is in the accuracy department along with its many other flaws , makes it  slightly more useful then tits on a boar hog. After getting the carbine hot  after some drills using the SOST and playing around, I fired off 10 rounds fairly quickly  with the Colt/18x combo.  The results left me a little surprised, rarely have I seen green tip shot for accuracy  with sand bags, a table and a target scope further then 50 yards. And I do not recall having seen any pictures of it doing as well in a true 100 distance group.  I shot the green tip with all seriousness and the same concentrated effort I did with the SOST and the results were pleasing and a little surprising to me.  I have never taken the green tip seriously  enough for my own needs in the accuracy department so this will indeed lead to more testing of the M855 if for no other reason  then to see if this was a fluke.

Now I do not mean to sound like I think green tip is crap, I have seen some  good performance out of it at longer ranges on coyote size targets and even man sized targets. But on the other hand, I have seen some terrible accuracy from it too. Of course lots and different MGGs have as much to do with it as anything, not to metion the different shoots and the quality or lack of  in the guns used.

Back to the SOST, I think its a pretty good round from what I can tell. It is not MK 262 or TAP 75 gr. But for general issue to everyone, it is an iprovement in my humble opinion.  I have not shot anything living with it yet, but I will. Also, in the next few weeks I will test it though a few “barriers” like auto glass, wood, and wall paneling. Hopefully I will get to shoot through some auto doors as well.  I would not use it in my own house if over shooting is a issue, but I would use it for anything else at this point if you can find enough for SHTF bulk storing. And you have the benefit of practicing/training with M855 and still being able to shoot the SOST without a zero change. At this point I can not say it is better then any MK 262 top load in accuracy, but it is not meant to be, but, it is better then M193 by a long ways and it shows the ability to shoot a lot better the M855 and even if it just matches it in accuracy you still have the benefits of better terminal performance and barrier penetration while still holding together to hit the target behind if power point presentations can be believed. Hopefully my future testing will offer at least a tiny sample to help prove or disprove the new round.

Springfield SOCOM II quick review

Today I got the chance to look over and to shoot the SOCOM II rifle a close friend bought. Anyone who knows me , knows I am no fan of the M14/M1A rifle. I will not go into the many flaws it has here, but I will say despite my dislike for the rifle I always give them a fair try and never slam one unfairly just because I do not like them.

The rifle arrived  with the companies 10 round mag. Why not a 20 round mag? I have no idea. The mags when new cost double or triple a USGI  Ar15 mag and I know most buyers would want a USGI 20 round M14 mag to start with. Though I do understand legality can come into play depending where you live.

The stock is a nice touch, it fit well and tight unlike some cheap fiberglass types stocks I have seen with huge gaps. The grip and forearm had a sort of checkering though I felt that other then looks, it was not aggressive enough to be used for real grip.  One thing I did appreciate was the mag well had a nice angled bevel to help inserting and rocking in of the magazine.

After picking it up and handling it, I found the balance to be pretty nice it shoulder well and was short and quick when moving it around tight spots.


The SOCOM was also one of the first M1As I had ever held that the top handgaurd cover fit nice and tight and not rattle around loosely like it normally does on a M14.  On top of the rifle in front of the bolt is a short piece of rail for optics.  This is an idea spot for a T-1 or RMR. I don’t think I would mount something as big as a CompM3 or Eotech, but it is a nice set up for the mini RDS.  Having no optics on had to try out , I can not say anything about  if it would co-witness with irons. The rear peep sight is bigger then the traditional rear sight. i appreciate this since I have never found the normal small peep to be handy for me at close range or moving targets. the frnt sight had a tridium vial and the protective hoods on each side of the front post are nice and wide, protecting it but not so close to cause confusion at night or in a stressful situation.

After shooting it and checking zero, we proceeded to do some faster shooting. the muzzle brake did its job well. Using Federal gold medal 168 grain Match, the muzzle stayed flat and reduced recoil with not much flash at all. However, with lake city ball, the muzzle blast would peel paint from a wall and was loud enough to be a real distraction. The ports on the brake did direct the worst of the flash away from the line of sight enough to reduce it. No night firing was done so I can not comment on how bad it would be at night with Ball ammo.

The gun was very controllable during double and triple taps.  A number or shots were fired at a  IDPA target at 25 yards to test how controllable it was during rapid fire.  A few double taps even manged to cut into each other or a least touch because of the effective muzzle device. Double and triple taps easily stayed on the head while firing as fast as possible  even fighting against the 2 stage trigger.

After having some fun and getting a feel how the rifle generally handled, we decided it was time to test if for accuracy. Since we where not on a range that let us shoot past 25 yards we had to settle for the short range.  two  5 shot groups were fired using the before mentioned federal gold medal 168 match load.  No optics were used nor any kind of tripod/bipod. I know it is only 25 yards and open sighted, but I have to say, it shows some real potential.

5 shot group 168 grain match

Both groups are 5 round strings fired with the Federal gold medal 168grain match load. As you can see in the pictures 3 rounds went into the same hole in both groups. Considering both were shot pretty much off hand, thats not bad at all  even as close as 25 yards!!

Now the downside of the SOCOM II is it suffers the same things as all its other versions. A very slow reload. A safety that is not in a good spot at all. In fact. with the smaller trigger guard and the position of the safety, I found ever time I tried to put my finger into the trigger guard, my finger got hung up  between the two and I had to take a second to make sure I got it in where it needed. Sure this is a training issue, but its a issue that really should not even really be there. Other small issues to me are miner, like having to clean from the muzzle and the gun not having a bolt closure or a better safety but these are all personal, maybe other who love the rifle will train hard enough to over come them and perform beautifully with it.    It is a very accurate rifle from what I have seen and it handles great. Plenty of companies make a rail or a way to mount what else you need on a general purpose rifle so there should be no problem there, And you can replace the stock with a multitude of other options. If you want a battle rifle that is  not too long, this is a good choice and its not as pricey as  some AR10 type .30 caliber rifles though you do not have the versatility of the AR type rifles, you still get one nice sweet rifle that is superior to the normal M14/M1a

Thoughts Magpul DVDs

PART I

Now that the magpul DVDs have been out for a while and it seems everyone has seen them, I have noticed a few common ideas about them people seem to have especially on internet forums.  A lot of people I talk to about them seem to miss some of what I think is the real point and value of them.  they obviously can not substitute for real hands on training, but they do have some real benefit despite what some say. Mainly I think the point lost on a lot of people is the video really help with weapons handling and manipulation. Even if you are a long time AR15 user, you can learn some pretty good stuff, even if you do not adopt  their procedures it gets  you thinking ( if you have enough brain) about cleaning up your own sloppy actions.

If you do choose to use their version of each operation its still some good stuff.  Its in style now to rag on them and make all the useless and pointless tier 1 jokes in a worn out attempt to be sarcastic, but in doing so, some real chances to learn are lost.  I for one have become a lot smoother with my weapons manipulations and have even modified some of what they teach to better fit me. You do not have to do it exactly their way but it is a great starting point for basic manipulations and smoothing your own self out.

Another thing people seem to  get the wrong idea bout is speed, or how fast they can put 5-10-20 whatever rounds out. We have seen a lot of guys shooting at ranges who seem to think the point is to get the mag half empty in 3 seconds even if they hit the dirt 5 feet in front of them!! The videos do not demand  1 MOA groups on target, but a balance between  speed and accuracy that is good but not slowfire at the NM good.   But it seems that because it is so cool to see those two guys  dumping rounds on target in seconds people just forget you also need to actually hit with those rounds. The more the offender seems to blaze away at a break neck speed,  the worse they were at just plain marksmanship to start with.  The idea being forget precise shooting I will just do a mag dump!  Few seem to want to train smooth a slow so they never gain the speed that  comes through the repeated movements done correctly.
