Fast shipping...have not shot yet

Velocity Ammunition was great

Delivered as promised, great to work with. Looking forward to my range day with the ammo.

UNSAFE - AVOID at all costs! Cartidges out-of-spec!

I had 5 or 6 misfires in 40 rounds, and the cases were getting stuck in the extractor lever. Turns out the cartridge outer diameter was so large that it would swage the base of the cartridge into a small flange!!! its a miracle none of them slam-fired with the cartidge at half-battery and fragging the right half of my face.

Over Charged Ammo Issue

So there is an issue with this ammo, IDK how they measure their charge amount but it's not consistent. Most rounds are good, some slightly over charged causing the rounds getting stuck in the extractor but you can just pull it out, and a few that are so over charged causing the round getting stuck to the chamber the bolt extractor. I had to go to the gun smith twice to unstuck my bolt and brass from my upper receiver.
