I'll start off by saying I have a Dillon 650 on its way so I'm excited about that. It's going to be a huge step for me because I'm using a Lee turret press.

My girlfriends father wants to load some 10mm for his glock. What is the go to powder for this round?

To me this is one of those odd ball rounds, like .357 sig. there doesn't seem to be a whole lot of places to buy 10mm cases like 9mm or .40.

I like Unique for medium power loads, although I never really experimented with these much.

For full power, I have had good luck with Blue Dot, Power Pistol, and Longshot.

I bought 2k Starline for brass.  It sucks shooting it because I'm usually almost as worried about where the brass landed as I am where the bullet hits

My favorite 10mm plinking load is 7 grains of Power Pistol pushing a 200gr Hornady HAP bullet.

The "go to" powder for me is Longshot.

Dillon powder measurer will measure spot on with it and it's quite the do all powder for 10mm.

I like AA#9.  I have also used Silhouette  and 800X.

I worked up loads with both Blue Dot and Longshot in 10mm, found Longshot to be easier to work with. Blue Dot can get weird up around max loads.

Thanks for the advice. I already have power pistol. I'll probably pick up some long shot too

Haven't clocked 'em while Glockin'. Like AJE I hate loosing brass, at least with the MP5 I can attach a brass catcher to it.

I like Power Pistol and Longshot with 180gr JHP bullets. Lots of people like AA#9. I like PP for medium to medium heavy loads.

Another +1 for Longshot.  I was hoping to get a few fore FPS our of Blue Dot but it wasn't what I was expecting.

I went through this a few years ago and ended up with Power Pistol. 

ETA: IIRC it burned quickly and didn't take up a lot of room (good for max loads). Was also flashier and more of a sharp crack compared to others, so more pizzazz at max loads if that's what you're after (most 10mm guys like big guns acting big).
