I've been reloading pistol and rifle for a few years and just go into 10mm this past summer. I have both the Glock 20 and 40 MOS and plan to stick with Underwood and DT for really hot ammo but I'd like to reload 180gr FMJ hotter than a .40 S&W but nothing in the nuclear category.

What kind of velocity should I be working towards? Would a 180gr at 1200 fps be considered pushing the limits of either stock Glock?

Welcome, Kramer.

180's at 1200 FPS is middle ground. I routinely load similarly for target fodder. They won't be any punishment for either of your pistols, and still a ways from full power UW or DT rounds. A bonus may be, you can use relatively fast powder for that load, meaning "cheap" target rounds in regards to powder consumption.

Welcome to the forum!  1200 and 1250 are easily obtained with the 180s with several different powders...be sure to review and study the 10mm Commercial Pull-Down section for details to help!  http://10mm-firearms.com/factory-10mm-ammo-pull-downs/

1200+ is a warm/upper load for a 180 gr bullet, but easily obtainable and really not pushing the limits.
There are many powders that will reach that.

Thanks for the replies. I've been using Alliant BE-86 for 9mm and 357 and I see their load data for the 180gr 10mm with a max charge a 8.6 grains. The velocity is right around 1250 fps so I figured I'd start at about 7.7 grains and work my way up to about 8.0-8.3.

1200 with 180 is a chip shot for 10mm.  Warm ground is 1300.

I'm getting 1,200 with a couple tenths over starting of Longshot

Though I am using an AM barrel.

An aftermarket barrel should be a little tighter resulting in higher pressures and slight bumps in velocity.

Is it even worth it anymore? I can get it cheaper than 45 now.

Well when you can reload 45 for 13-15 cents apiece plus your brass investment, I guess it would be.

FMJ? 

You are going to be into that about $170/K not counting brass.  Practice reloads like this you should get 8 reloads before you loose/split the brass, so that adds $20/K for brass.

Casting + powder coat is the place for real savings.  In that game I can get down around $80/K including brass at 8 reloads before it is done in.

I was thinking powder coated lead in my figures above.
Primer three cents
Powder would be three or four cents on 10 mm
(One cent on 45)
Bullet  would be nine cents
Brass depreciation would be 2 1/2 cents

18 1/2 cents per round
$9.25 Per box if I did the math correctly in my head

I save all my 10mm 357 sig and 38 super ammo. I plan on reloading in the future. I think it's a good skill to learn.

The initial setup is semi expensive but I do see the cost savings if you get more shots per case.
