I recently added a KKM barrel to my Glock 40 10mm. I have killed a deer in the past with it and hope to shoot one this year too.
I loaded some 180gr XTP with Longshot and a CCI 350 primer.

I shot some today to test the loading.

I’m attaching pictures on the primer and the chrono reading.

I know I won’t be going any hotter.

No accuracy tests yet.

Let me know what you think.

One shot test?
Primer looks "somewhat reasonable" to me. Some flow, too much, can't say.
6" barrel on the Glock 40 - right?
How many grains of Longshot? Or, keeping us guessing?

Yes 6” KKM Barrel.

Had trouble with the trigger at the range, changed the striker spring back to stock(had a ghost set up in it before) when I got home and just shot a few rounds in the backyard. Didn’t want to piss off the neighbors too bad.
Will shoot the rest of the ammo I loaded this week when the range reopens.

Started at 7.5grs and went up to
9.5 grs of Longshot with 7 rounds of each.
