180 Grain Coated lead with Longshot

[aOWENc]

Hey everyone!

I used the search function and found some results on this, but I'm a new reloader  and was hoping someone could maybe give a but more of a definitive max charge or starting point for my particular setup.

I'm shooting a Glock 20 with a KKM Barrel. I just got a chronograph as well so I'm looking forward to reporting back with whatever results I get.

I was hoping to pick up some blue dot and Accurate #9, but my local store only had a few pounds of longshot so that's what I'm rolling with.

I'll be using mixed brass and Remington large Pistol primers.

For bullets I have some 180 grain coated FP from Hoosier Bullets. He's a preacher that lives about an hour away from me in Indiana, and he makes a great product for a really good price.

I'm currently planning on starting at 9.0 grains and doing a plunk test with my barrel, my manuals show a minimum OAL of 1.250" for 180 grain lead. I will then work up a latter test and hopefully be able to get 1250 FPS safely.  How does this sound to people with a lot more experience than myself?

Any additional advice or recommendations would be greatly appreciated. Thanks guys!

Hoosier uses Hi_tek powder coating and I use TMJ/FMJ data (as do most I've read about) for all my powder coated bullets. Start on the low side and stay in listed loads for copper and I think you'll be OK.

KKN says: "Our Glock barrels come with fully supported SAAMI spec match chambers for shooting factory or reloaded ammunition as well as lead or jacketed bullets"

Good stuff there.
