Hello
Recently tested True Blue and N350 with a bone stock Glock20-SF, using Hornady 180 HAP bullets, in 0.3gr increments miking cases for pressure.
And shot a few feeler loads with BE-86.
Data on the targets from top down;
velocity
extreme spread
standard deviation
temp F°
Everything was shot at 25 yards. Circles are 5½" Std 25 yrd pistol target black.
N350:

N350 shot well in this gun. Even the 9.2gr load, which was a little hot for this gun, shot nicely. I was especially pleased with the low standard deviations.
In this gun 8.9 or 9.0grs is as much as I would want to load.
As for True Blue, I couldn't hold groups very well. However the standard deviations were equally impressive.
Got smileys at 9.7grs and 9.4 was pretty warm.

BE-86;
Alliant shows 8.5 grs in their loading data and they list a velocity of 1265 fps
Well that didn't quite happen in this gun.

Miking the cases indicated that this was not a max load for 10mm. So I shot two more increments of 0.2grs.

With the CCI primer the standard deviation was quite good. Groups were ok, but not as good as N350. I stopped here for now. Case measurements indicate maybe one or two more increments.
Here is a spreadsheet of where I'm at with the Hornaday bullet;

When I start to see .4342" when working up, it's time to stop. I've never seen a miked case of .4346" or larger that wasn't a smiley.
Of course everyone knows that data developed in one gun is necessarily going to duplicate in another. One should always work up loads carefully in their own guns.
Oh oh... pics are too big?? I'll have to edit. sorry
RDub01, I accidently pasted the resized chart over you first pictured target. Sorry about that could you repost that first target picture link so I can fix it...or you can modify your post to paste the link back in there.
