I managed to get to the range and tested 8.5 grains of BE-86 under the 180 grain Rainer HEX HP, CCI350, Federal (pass through reconditioned) brass, COAL 1.254"
These were tested from the Glock 20SF factory 4.6" BBL with the non captive Wolff recoil rod using the 22lb spring.
Velocities were 1219 / 1197 / 1173 from the three tested.
Alliant shows 8.5 grs in their loading data and they list a velocity of 1265 fps
My data matches up with RDub01 test - Hornady 180 HAP with 8.5 grains BE-86 Federal 150 primer @ 1187 fps (18-Sd / 8 ES 47 degrees)
I suppose my CHRONY is working OK since I shot it and put it back together... ::)
I want to test the Sig Load 180 FMJ 8.8 @ 1250 fps next time out
Good report. Looks like this is a good powder, but delivers under max performance for 10mm. At least on book loads
That matches up fairly close with my results in the 5" Rock.
8.2 gr BE-86
180 gr XTP
Starline brass
CCI #300 primer
1140 f.p.s. (Alliants online data shows 1256)
I was hoping the low velocity was due to the poor barrel...guess not.
I'll revisit this load in the G40 when I get a chance.

With the Rock back from the mothership I took advantage of a beautiful December Sunday with overcast sky's, temps in the upper 50's and no wind.

Have you tried pushing this powder any faster?
I haven't got to test much yet, have stuff to go test but finally the time change and weather are aligning to make it doable soon. :-[
I just got 2 pounds of BE-86. Looks like I will need to go max to operate the AR.
