Hello Everyone,

I just have a quick question on the legality of PMC X-TAC LAP rounds? I saw where armor piering rounds are illegal for NJ in a pistol but are legal for a rifle which in 5.56 is considered green tip ammo. Does anyone know the legality of the X-TAC lap round since they do make a very few pistols in 223 such as the AR15 pistols? If they are legal can someone please show me the law where it states that its legal. Thank you for your help!

They are legal, as to showing you where the law says they are legal your not gonna find anything. The law only states whats illegal, and wheres the law that says these are illegal?

They are not true armor piercing rounds anyway.... True AP has a tungsten rod inside. The LAP bullet has a little steel cone at the nose. I think by light armor piercing the military was referring to car doors and the like.

The federal definition is a lot more broad than that. But SS-109 projectiles (M855 style ammo) is excluded by name to avoid confusion.

It's not light armor piercing, it's not any armor piercing, it was designed to penetrate a helmet a hundred meters or so further than plain old lead M193 when NATO came up with a standard for 5.56mm. The small steel insert is mild steel and it's not even pointed. The designers said it was to control yaw at impact at the specified range of the test.

Interesting... with my limited knowledge I always thought they were armor piercing... So, this is good info to know. We were playing around with M855 ammo at my buddy's place out in the mountains of PA just recently and were able to blast holes through a 3/8" thick steel plate. It was Lake City XM855 green tipped rounds... We also tried XM193 and it only put small dents in the steel plate.

 

EDIT: Forgot to mention that we were shooting at the steel plate at 100 yrds and were putting holes through it with the XM855... Maybe it was a soft steel???

I thought the X-TAC 62 GRAIN LAP stood for Light Armor Piercing? Thank you everyone for your help! So by NJ'S definition what do they consider a handgun calibers?

Works great on windshields too!

Definitely was soft steel but yeah M855 will penetrate better than XM193

M855: Defined in MIL-C-63989 NATO specifications for M855 Ball require a 61.7 grain (q 1.5 grains) with a hardened steel penetrator at a velocity of 3,000 fps (q 40 fps) from a 20" barrel @ 78 feet from the muzzle. Typical velocity 15 feet from the M16A2's muzzle is 3,100 fps. Accuracy: maximum of approximately four MOA over the 100 to 600 yard range. Typical accuracy of average lots in an M16A2 is about 2+ MOA. This round must also penetrate a nominal 10 gauge SAE 1010 or 1020 steel test plate at a range of at least 570 meters (623 yards). The M193 round will penetrate this same plate reliably at 400 yards and about half the time at 500 yards. The 5.56mm and 7.62mm NATO rounds will penetrate it reliably out to 700 yards or more. Because the steel penetrator increases the length and changes the weight distribution of the SS-109 bullet, it is suitable for use only in barrels with a twist of one turn in nine inches or faster. 1:10 twist will barely stabilize this round and not below zero degrees F.

 

BTW 10 ga steel is just over 1/8" thick

Actually, M855 will not penetrate all steel at all ranges better than XM193. And it will not penetrate all other materials better at all ranges. It does tend to penetrate thin metal better at most ranges. Mostly because it has greater sectional density. The small steel insert may help a little with penetration, but it's primary purpose is to control yaw at the design test range. Look at any AP round (military definition) in any caliber - all of them have sharp, pointed tips to their steel, tungsten, or whatever components. The SS109 projectile has a small MILD steel insert with a flat tip. Nobody has ever made an AP round that way, and nobody has ever claimed the round was AP, and it's not even slightly AP. Further, most AP round have something OTHER than steel or tungsten at the tip. Often lead, sometimes incendiary. See if you can figure out why for extra credit.
