https://greyhive.com/videos/watch/5ede95e4-43c8-4deb-9d64-c0d6dcae64d5 I happy to present to you the 80 Teeth 40gr SM855 5.7x28. Instead of 62gr 5.56 you’ve got 40gr 5.7 with a moly coating. The moly coating is designed to assist in feeding. As you will see the ammo feeds successfully suppressed in the CMMG Mk57 Banshee rifle. As well as the accurized FN 5.7 MK2 pistol. To see a full length video of this exact ammunition minus the moly coating. Check out the Buffmanrange channel. Type in 40gr SM855 5.7 Buffman. It should come right up then. He chronographs the ammunition for velocity. Also tests it against 3A body armor which it defeats. Thanks for watching more to come soon!
