There were several cases of it up at Scottsdale Gun club last week.

From my perspective, I am looking for a subsonic 300 blackout round that the bullet has great expansion or perhaps it is a frangible bullet at the speed that is design for. I have not seen a decent expanding subsonic bullet yet, perhaps I am not aware of the latest. If you know of any, please sound off.

Have you not checked out the Lehigh Defense bullets? The 200gr ME bullet did really well.

Review time on these yet? Love the channel you got, very professional.

I bought a box and they cycled just fine in my Noveske 10.2". I don't have any gel to test the expansion though. I pulled one apart and it looked like A1680. Weighed an average of 10.6 grains. It was definitely dirty like A1680 when I shot it! Who knows though. The gemtech's were shooting around 950fps with a low of 820fps and high of 1000fps. So they weren't that consistent (or my chrono sucks.) the accuracy was average. If you don't reload, these will be good. If you do reload, don't bother with these as your own bullets should do a lot better than these. IF these expand, then they are worth it just for the fact that expanding heavy pills cost as much as this ammunition costs.

With that said, I shoot nosler CC 190gr pills with 11.5gr of A1680 and they have never given me an issue in my AR 15.

Found these in stock. Debating purchasing a case, but still seems a little high on price.
