8.2 grains of Longshot, 200 XTP...

Not so good.

1,261 fps...64 fps more than the stock barrel with the same load.

ES 37, SD 15

I think I'm done fiddling around with powders.

AA #9 is gonna be my 10mm powder with 200 grain bullets.

And Power Pistol for everything else (plinking and practice), likely some Unique too, since I have a couple pounds.

I'll burn the Longshot up in some 12 guage hunting loads.... I'm just not liking it much in 10mm.

Also, I don't see the point in pushing the limits any further with AA #9.... My only goal with this is a good powerful load that won't have me flinching because I'm wondering when it will Kaboom on me, lol... After all, speed is fine, but accuracy is final.

I'm just gonna roll on with the 12.6 grains of #9.

Load development done.

Next up, sighting in.

I have a 9" Lone Wolf barrel :o  I'm just waiting to find the right deal on the Glock 40...could save some $$ by putting into a 20, but I do like the aesthetics of that 6" slide!

Quite a few rounds through the 7" KKM now...still no malfunctions of any kind....runs like a top and accurate as can be.

Would I?  I did!  And I added a couple of extra inches just to be on the safe side  ;D  For some reason, I keep thinking that if it stays like this for more than 4 hours...I'll need to see a gunsmith!

The 1st pic is the 1st 3 shots before I sighted the DeltaPoint-Pro in; the 2nd one is the 1st 3 shots out of the stock 6" barrel:  I was surprised at the difference in Points-of-Impact.

I put mine on today. I got the same results the groups shrunk right up. I am running a RMR on my Glock 40. I was shooting 200 grain GC WFN over 7.9 grains of Power Pistol. I will shoot them over the Chronograph tomorrow. The 180 GD that reloaded ran real tight groups as well very close to the same POI as the 200 grain cast at 30 yards. Awesome so far and very pleased.
