Here is what is on the online retailer's website:

HPR ammunition is manufactured in Payson, Arizona using the latest equipment and technology to meet SAAMI Specifications. Every stage of ammunition production is carefully and directly handled by highly trained ammunition technicians and quality control inspectors led by their talented engineering staff. All testing is conducted on the finest testing equipment in the world to ensure SAAMI specification are met or exceeded. Each loaded round that is manufactured by HPR has a 1/10 grain of powder drop consistency, is visually hand inspected and chamber gauged, hand packaged and each box is traceable by lot. One of the great things about HPR ammunition is that they strive to use ALL AMERICAN components in their cartridges and even ensure the packaging is 100% American Made.

The Hyper Clean line of ammunition is loaded with HPR's HyperClean technology which is a combination of cleaner-burning powders and primers helping to ensure that firearms stay cleaner during extended range sessions. Each round is also loaded with quality components. This ammunition is new production, non-corrosive, in boxer primed reloadable brass cases.

This ammo was shot out of a stock Glock 20SF.  It came nowhere near 1270 fps.





Powder charge 10.8 grains;



Close up in pan;



Close up in bowl;



Primer;



Bullet; Hornady 180 JHP;



Any guesses as to what powder this is?

It's very nice looking ammo.  Clean, and shoots and feeds well.  Too bad it's not up advertised velocity.

Our old pull-down showed 11.0 of #7.

What velocity did you get?

Hello RDub01, its been a while.  Glad you were able to drop in and post the info.  To me it looks like AA#7, and based on the charge weight it fits the load data, however I don't know if it would make that velocity as advertised... :-[

Yep, finally got the shop built and a reloading room finished. :)

The velocity is on the target pic underlined. If the pic isn't showing up it was around 1115 fps... don't have my notes here at work.

That seems extremely low even compared to other #7 loadings >10.0grs.

The pic should show up now..

Yes, I was quite surprised with how far the actual was from the advertised velocity.
Makes me want to pull em all down and put in a descent charge of something.

Posted a review over at Midway.. gave it a 3.

Oh, Shadow did you still want a pic of 300-MP?

I only got 1070 fps with these over my chronograph. Granted it was out of a G29. I expected more.
My neighbors dog has been telling me some very disturbing things lately. I just ignore him because everybody knows that dog is crazy.
