Help analyze 10mm load data

For what it's worth (Not much ) IMO the 6.9 load looks better. less side to side mostly vertical. Some touching! Yea (not bad shooting )
Just curious, did you change your point of aim on the first target? Maybe because the first ones were high?
I know I do this without thinking about it (and sometimes when I am thinking about NOT doing it) when testing some times.
Shoot, shoot, shoot, rats. I did that here, little low and left aim higher and right to hit center, ooopss did not want to do that......sigh
the group would have been better if I did not change my POA. I tend to think we all want to hit the center and make the adjustments without thinking about it sometimes.

Power pistol makes such a nice flash
Almost as loud as Longshot in 9mm. (longshot is loud)

Don't know what the min and max for that load combo is but I would be tempted to maybe try 6.7 just for the heck of it.
I shoot paper targets for fun and don't need to make a PF.
The 9mm Titegroup load below is actually about .2 below the start load from Hodgdon. Functions Full size Springfield 9mm 1911.
(shoots really soft by the way)

The first one for sure. Work around that load and skew up and down by 0.1 grains at a time. At the ranges stated, those are some good groups on all of them.

More info.

Distance?

Off hand?

Bench rest?

Bullet and bullet weight?

Personally I can't shoot off hand well enough with a pistol or a rifle to determine the most accurate load.

When working up loads, I try an eliminate as much human error as possible, that means a rest of some kind. YMMV

Seems light. Alliant lists 10.0 gr as max with the 165gr GDHP. I did not notice your bullet weight in your initial post.

By all means use a rest when testing ammo.....you will definitely get a better idea about your loads...

IME, Power Pistol gives the best accuracy in the mid-upper spec of the load range. Hard to gauge accuracy at such short range without a rest or sandbags.
