A savvy shooter can tell what is special about this 7.62×51 ammo by Sellier & Bellot at first glance. Two hundred grains is heavy for a 7.62×51 bullet, which is typically closer to 147 grains. That big boost in mass accordingly makes this round subsonic!

So large a bullet can’t pick up enough speed to shatter the sound barrier upon darting out of the muzzle. At 1,000 fps, it’s not going to make an exceptionally loud cracking report. It’s a great way to appreciate the real potential of a suppressor, but do take care that you’ll still need ear protection while you tear through this ammo.

This round’s bullet is a full metal jacket. You want no less for a semi-auto that demands a hard bullet to feed without jamming, especially when it has a suppressor full of baffles that are no fun to clean lead residue off of. With its reduced muzzle velocity you’ll notice that so substantial bullet doesn’t offer a very flat trajectory, but hey – that’s the price you pay for subsonic performance!

This round’s reloadable brass case is fresh out of the factory. You can likely tell from looking at it that it is correctly annealed. This proves it will seal the chamber effectively during ignition, not that it has been reloaded. And speaking of sealing, that’s exactly what this round’s sealant does to its non-corrosive primer.
