Y'all, I apologize if this is a dupe or asked in the wrong place. Mods - please Move/Delete at your discretion. I have fired several hundred rounds of NATEC PCS Spectrum ammo pretty much since it came out. I bought a bunch of it and have been shooting it here and there since with no problems at all. The last two times out, and in a total of maybe 40 rounds, I have had one partial neck seperation with a blown primer, one blown primer that functioned/cycled properly, and one complete neck seperation with blown primer that jammed up the rifle with the neck still in the chamber. The rifle being used was a Rock River 16" Midlength with a chrome lined barrel. It functioned fine with UMC 55rg FMC, LC M855, and an assortment of others. I put all the ammo on stripper clips, so I don't know if they all came from the same box or not. The cases were grey polymer. So what's the deal? Why would I have no problems at all, and then suddenly have so many problems with so few rounds? Either way, I won't be buying any more.  -K |
| I found this ammo to be total crap. I have had a Colt H-Bar 20" since 1992 that has not had one single failure of any kind until I fed it this crap. I would assume that their quality control was lacking seriously and that the ammo is very inconsistent. Would also not run in a Bushmaster carbine. I would not give 50 cents a box for more. |
It's a great weight savings, and likely a cost savings too. They have to figure the whole case of some sort of polymer though, so the brass doesn't get ripped away from the plastic, like it can with the current product. They need to design it so only the primer and the bullet is metal, with, perhaps, polymer staking for the primer. They also need to design something into the case to prevent the bullet from getting pushed back into the case, which I would suspect could be a problem with the polymer case. |
The problem most experience is the neck cracking away. not seperation of the brass from the rest of the casing. That said, I have fired thousands of rounds of their commercial and military cased thru M16s with no issues. The military cased stuff has notably stiffer cases (haven't sectioned any yet, so unsure if it's thicker) but both have worked for me. I'm actually starting to think chrome lining may be the reason they work (and the lack of it results in torn case necks...) |
Caseless was way ahead of its time. I think we will see caseless ammunition in the future, in fact the armies next generation LMG program is running a caseless version in competition against a polymer cased telescoped round. The problem with caseless is the thermal management issue, with out the ejected casing acting as a heat sink and removing heat from the weapon you have a gun that gets very hot very quickly. I think that modern materials have advanced to the point that this problem can be overcome, but that doesn't do anything for existing weapons. Polymer cased rounds on the other hand are a nearer term solution and are 'backwards' compatable with all the weapons we already own. They also prehaps represent a path back to cheaper ammunition. |

There used to be an entire thread on this with ammo tried, guns listed, groups, etc. Maybe if you are a member you can search back beyond 30 days to retrieve it. I just fired 120 rounds througha vietnam era AR (no problems), and my FS2000. I had one base separation on the FS2000 and the baseless round jammed halfway into the chute. The other round got mangled halfway to the chamber. I opened the hatch and used a needle nosed pliers to tear the casing out of the chute and cleared the rifle. No other problems. I like the stuff and will buy anybody's who has it for sale at $150/1000 shipped to 55056. email here: [email protected]. |
