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

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.















Note to RDub01, these were hosted in Photobucket, I copied them in to my postimage so these wouldn't be lost...

Our old pull-down showed 11.0 of #7.

What velocity did you get?

[The_Shadow]

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...

[RDub01]

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.

[Intercooler]

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

[RDub01]

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.
