Looks like quality. - Sellier & Bellot Subsonic .300 AAC Blackout 200 grain Full Metal Jacket (FMJ) Subsonic Brass Cased Rifle Ammunition

First off I want to say the quality of ammo in the past five years or so had gone down extremely especially when Covid hit and has continued to get worse. But gladly S&B are an honest company that cares about the products they put out. Winchester white box 300 ammo is the complete opposite as I ordered five boxes and is the wirst ammo I’ve ever seen in twenty plus years. The ammo had sealed primers which is a great convenience and always smart to have done. Only thing is a few rounds per box of this S&B the sealant around the primers didn’t make it to where it needed to go so not all are properly sealed but most are and the ammo itself looks just fine with zero issues. So don’t think S&B isn’t a top notch ammo maker as they are better than most well known names like Winchester that sells pure trash these days. See my review on the white box 300 rounds on that page as it’s important you read it to possibly save yourself from serious harm or death Orkney’s weren’t seated at all correctly and wrong projectiles put in a lot of what should be used. I have pictures to prove it all.
