Description
There's not much in the ammo world that turns heads quite like a can of linked .50 BMG. PMC built this Bronze line load around a 660 grain full metal jacket boat tail bullet, seated in brass cases and strung together on links so it feeds right off the belt. It comes packed 100 rounds to a steel M2A1 ammo can, the same style container that's been protecting .50 cal ammunition for decades, so you get a load that's ready to run and easy to store or haul to the range.
Bronze Linked 660GR FMJ-BT Build
PMC makes this ammo at the Poongsan facility in South Korea, where the company controls its own brass, bullets, and propellant rather than sourcing components from outside suppliers. That kind of vertical control tends to show up in consistency from round to round. The cases are boxer primed brass, non-corrosive, and reloadable if you're the type who likes to get a second life out of once-fired .50 cal brass, which given the cost of feeding a .50 is a real perk for a lot of owners.
Ballistics on the 660 Grain Load
This load leaves the muzzle around 3,080 fps and generates energy figures north of 13,000 ft-lbs, putting it firmly in territory that dwarfs nearly every other cartridge on a sporting goods shelf. The boat tail design on the bullet helps it retain velocity and buck wind better than a flat base bullet would, which matters when you're stretching a .50 out to distance. It's a ball round through and through, built for feeding reliability and flat shooting rather than match-grade group sizes, though most owners find it groups plenty well for the kind of shooting a .50 gets used for.
Linked and Packed for Belt-Fed Guns
Since these rounds come pre-linked, they're built with belt-fed platforms like the M2 Browning in mind, dropping straight into the gun without any extra prep. If your platform is a single-feed bolt gun or a semi-auto like a Barrett, the rounds can be pulled from the links and fed individually, something plenty of .50 cal owners do without any trouble once they get a rhythm down. Either way, the M2A1 can it ships in isn't just packaging, it's a genuinely useful piece of gear on its own for keeping ammo dry and organized long after the rounds are gone.

Frequently Asked Questions
What guns is this linked .50 BMG ammo meant for?
This load is linked specifically for belt-fed .50 cal platforms like the M2 Browning, so it feeds straight off the belt without any prep work. If you're running a single-feed bolt gun or a semi-auto like a Barrett, the rounds can be pulled off the links and loaded individually, which plenty of .50 BMG owners do regularly.
Is the brass on this PMC Bronze linked ammo reloadable?
Yes, it's boxer primed, non-corrosive brass, which means it's set up for reloading once you've fired through it. Given how pricey .50 BMG components can get, a lot of owners end up saving their brass specifically for this reason.
How hard does the 660 grain FMJ-BT bullet hit compared to other 50 BMG loads?
At 3,080 fps and right around 13,688 ft-lbs of muzzle energy, this is a full power .50 BMG load, well above what most other centerfire rifle cartridges produce. The boat tail design also helps it hold velocity and buck wind better at distance than a flat base bullet.
Can I use delinked rounds from this can for precision shooting?
You can, and plenty of shooters do delink this ammo for use in single-feed .50 cal rifles. Keep in mind this is a bulk ball load built primarily for reliable feeding and volume shooting rather than match-grade precision, so accuracy will be solid but not quite what you'd get from a dedicated match load.
