Georgia Arms 10mm Ammo

[atblis]

I was bugging GA about their "+P" 10mm ammo. They claim a 180gr at 1150 fps on the package (if there was a 10mm +P that wouldn't be it). I chronoed it at 1040 from a Witness.

Anyways they emailed me back with this response.

Andrew, sorry for the delay, I just downloaded this email from our server. You are correct, that velocity is wrong for the 10mm 180 Gold Dot load. I am not sure what the problem is but I looked back at the last several lots we ran and the velocity averages around 1176 to 1200 in our test gun which is an S&W 1006. We did reduce the pressure on this load from about 6 or 8 years ago as several guns on the market have a huge feed ramp that creates problems with case expansion. (The Colt Double Eagle and Glock 20 come to mind.) Is it possible that the ammo is misslabeled? I will be happy to swap the ammo out for you. Thanks for the input. Curtis

Does anybody see the possible irony in the Glock 20? It's in a way keeping the 10mm cartridge alive, and yet killing it at the same time.

Hmmm, sounds like someone is using a non existing conditon as a scapegoat for his poor ammunition. If he want's performance withotu pressure he needs to use a slower buring powder. Most likely he is using a faster buring powder because it is cheaper and doesn't want to change to a slower burning powder that he will have to use more of.

If the G20 is so bad, how is it that I can shoot a hanloaded Hornady 200 gr. XTP out of my factory G20 (with factory barrel) at 1,275 fps? I shouldn't be able to do that if you are to believe this guy. How I did it is to use toe correct powder and load development.

I get tired of people using myths to cover up their problems.

The Glock thing

it appears that the feedramp thing is only part of the Glock problem. Some Glocks seem to be worse than others.
