This morning was search mode again.

http://www.precisiondelta.com/detail.php?sku=EP-10-180-FMJ   Kind of weak looking.

http://www.sharpshooterammo.com/  I have no idea on this one but e-mailed them.

http://www.sheepdogammo.com/index.php?route=product/product&path=61&product_id=104  They claim 1275 FPS. I sent them an e-mail to see if it was an 8" barrel. If the claim is correct that is a 600lb member

http://www.summitammunition.com/   They don't list 10mm on their site. I do know for a fact some YouTube shooters use it exclusively so I sent them an e-mail. Would require sending in 10mm brass I would think.

Wow.  I actually like these botiques toying with the 10mm even if not full house loads.  I may never buy most any of it, but it's always nice to see more enthusiasm toward the 10mm than less!

       Sheepdog said a real 1275 out of a Delta. In a Glock it may be a little less.

Waiting for a fifth supplier but he has his own Chrony data. Should be interesting!

Hmmm.  I wonder if it would clear 1300fps from your 6" Hunter.  I guess a 180 at ~1250 from the G20 isn't horrible, but I wouldn't be writing home about it either.  Just a decent load in my mind with a little yet to be desired.

The fifth one said 1200 FPS from a 5" barrel. Hmmm. Don't know if any are worth the test.

Yeah, after further thought I expect you're right.
