how could an 84 grain possibly be rated at +P and only be traveling slightly over 1300 FPS? that seems pretty lukewarm for an extra-light +P load to me.

Not my cup of tea for a 9mm SD load since I prefer "subsonic"/"heavy-for-caliber" bullets, but interesting, nonetheless.

Kinda surprised by both the excellent weight retention and penetration, though.

Are these being imported again?

Exactly. The 124 grain Gold Dot +P from DoubleTap gets right about that velocity. Standard 115 grain bullets are faster than that in +P from almost all manufacturers.

That may have something to do with the hole in the center of the bullet. It extends all the way through to the base. The gas driving the bullet is at its theoretically highest pressure at this locatoin, so propellant gas leakage is most severe at this area.

Looks like an all-copper bullet. Interesting. The Europeans seem to be big on expanding all-copper and all-brass bullets, that avoid being JHPs on a technicality. Like the German thing with a plastic nose cap that blows off, very similar to that GECO thing, and some other thing with a gigantic post inside it, like a Hydra-Shok on... performance enhancing drugs.

Where can one find this ammunition?

Me too until I saw expansion.

I have personally loaded the 90gr Speer Gold Dot intended for .380 Auto at 1500+ from 9x19, and these were not max loads.

Hmmm...very interesting. See...I am not part of the heavier & slower faction. Leave that to the .45 ACP. As I understand it, the 9mm is a high pressure round and it just shines at smaller and faster....much faster. I think all copper tops is the future in all cartridges...and I'd love to see a side by side test of this round with the 115 grain Corbon DPX + P in a compact frame with short barrel 9mm platform.

it's sold out. Thanks though. What was the price?
