Got out to chrono some loads today and got some impressive numbers, especially with my 6" Fusion.
I shot a ladder out of my G20SF (stock 4.6" bbl, Wolff 22lb RSA)
I also shot one round of the the max AA9 load from my Fusion 6" 1911 Hunter.
200gr XTP over Accurate #9 (the newest version of the powder, flattened ball)
CCI300 primers
new Starline brass
92 deg, sweltering
Here are the numbers....
Data format is as follows: LO-HI-AVG-ES-SD
I'll be measuring the cases later but no smiles and no obvious signs of pressure other than some normal swelling from the G20 loads.
12.4gr
1147-1183-
1161-36.4-15.9
12.6gr
(error, accidentally shot these on the prior string, corrupting the data ... I did see small velocity increase as expected, FWIW)
12.8gr
1169-1197-
1185-28.2-11.9
13.0gr
1187-1211-
1201-23.7-11.5
13.2gr
1215-1220-
1217-4.2-3.6
The following string was from my 6" Fusion 1911 Hunter
13.2gr
1360-1382-
1371-21.9-15.5 <--- HOLY SCHNEIKIES!!!
I'm a little skeptical of this particular string. I WAS a good 12-14ft back from the chrono so I believe this to be good data... but I will be revisiting this one. I would EXPECT about 1260-1290fps going from the 4.6" to 6" so this is a little surprising Very high numbers from the 6" fully supported Fusion barrel. Absolutely no case swell and the load felt really good... less recoil that I remember my nuclear Longshot loads in the same pistol that didn't get this level of velocity. I'm guessing that the combination of heavy bullet, slow powder and new cases allowed this load to really build up some steam.
I will be loading lots more of the 13.0 and 13.2gr AA9 / 200gr XTP's for further accuracy testing with both the G20SF and the Fusion for deer season this fall. Smasher of a load and, from what I've seen with OTHER Accurate loads through this Glock, will probably be EXTREMELY ACCURATE with low relative pressure.
I also fired a quick string of 13.5gr AA9 over a Rainier HP from the G20SF. Here are the numbers.
13.5gr
1129-1236-
1188-106.9-45.5
This load seems a bit slow since I thought it would be making 1200+ on every shot. I'll probably shoot a few more of these to double check for consistency. SUPER accurate load though, as I shot quite a few 1" groups with the G20SF/FF3 at the range on my last trip.
I also have quite a few more loads to test using both WSF and 800X (IMR) but that will have to come later. It was too hot today and those results will obviously be in their proper respective threads here on GT 10mm loading forum.
Here are a few pics of where I was shooting today....

Have a good one, guys!
