Description
PMC has been cranking out mil-spec ammunition since the early 1980s under the Poongsan Corporation banner in South Korea, and the X-Tac line is where that background really shows. This case gives you 1000 rounds of 62 grain Green Tip FMJ, split into 50 boxes of 20 so you can grab a box for the range bag or just keep the whole case stacked in the closet for whenever you need it. It's loaded to 5.56 NATO pressure specs rather than the milder .223 Remington standard, so it's built to run in 5.56 chambered rifles rather than bolt guns marked .223 Rem only.
The Steel Core Story Behind This Green Tip Load
The green paint on the tip isn't just for looks. It marks this round as an M855 style load, built around the SS109 bullet design that NATO adopted decades ago to punch through helmets and light barriers at extended range. A steel penetrator sits inside the lead core under a copper jacket, which is what gives this 62 grain bullet its reputation for barrier performance compared to a standard 55 grain FMJ. Keep in mind that steel core means it'll stick to a magnet, so it's worth checking with your range before bringing a box in if they're picky about that sort of thing.
What's Inside The PMC X-Tac Case
Every round in this case rides on new production brass with a Boxer primer, so once you're done shooting you've got cases worth saving if you load your own ammo. The primers and powder are non-corrosive, and shooters consistently mention how clean this stuff burns compared to some other bulk options, which means less scrubbing on your bolt carrier group after a long session. At 2920 fps out of a 16 inch barrel, this load stays plenty flat for target work inside a couple hundred yards.
Getting The Most Out Of The 62 Grain Bullet
That heavier 62 grain bullet wants a faster twist barrel to fly straight, so it does best in a 1:7, 1:8, or 1:9 twist AR-15, which covers the vast majority of factory carbines on the market today. This is a training and practice round through and through, not a match load, so expect solid function and dependable accuracy rather than pinpoint groups. Steer clear of steel targets and indoor ranges with this one since the steel core can spark or chew up equipment that's meant for lead core ammo only.

Frequently Asked Questions
What does the green tip actually mean on this PMC X-Tac 62 grain load?
The green paint identifies this as an M855 style bullet, built around the SS109 design that pairs a lead core with a steel penetrator insert up front. That steel core is what gives this 62 grain load better barrier and long range performance compared to a standard 55 grain FMJ round.
Can I shoot this ammo on steel targets or at an indoor range?
This isn't the load for steel targets or most indoor ranges, since the steel penetrator core can spark or beat up equipment designed for standard lead core ammo. It's a better fit for paper, cardboard, or outdoor ranges that allow steel core rifle ammunition.
Is the brass from this PMC X-Tac case reloadable?
Yes, every case is new production brass with a Boxer primer and non-corrosive components, which makes it a solid pickup for reloaders. Just keep the steel core bullets separate if you're planning to reuse them since they behave differently than a standard lead core projectile when resizing and seating.
What twist rate does my AR-15 need to shoot this 62 grain load well?
This heavier bullet wants a faster twist to stabilize properly, so a 1:7, 1:8, or 1:9 twist barrel will handle it fine. Most factory AR-15s already ship with one of these twist rates, so it's a safe bet for the majority of 5.56 chambered rifles on the market.
