I tried some AA#7 for my first reloads on the 10mm, and was using a 135 grain Nosler JHP. 13.5 grains, and averaged 1422 ft/s.

I've had some new Starline brass on order for a few weeks, and now FedEx should deliver them tomorrow. I am filled with quite a bit of anticipation there.

Also took delivery of some IMR 800-x powder last week, and after reading the 10mm reloading section on Glock talk (I have a 20 now also), I will be working up loads for 155 grain JHP's, and also 175 grain boolits. Need to cast up some more water dropped boolits this weekend, as I have them all loaded in 40 S&W cases right now.

Once I got that 10mm, my interest in the 40 S&W went on the back shelf pretty quick.

Did you get an aftermarket barrel, with the regular rifling for your lead boolits? I got the Lone Wolf, and very pleased with it so far.

well you do know what the S&W on the 40 stands for right? Short and Weak!!! I love the 10mm round.

I have just used my stock barrels on all my glocks with lead. I dont run cast boolits fast and I do clean the guns after every time out. Shot over 7000 rounds of lead in my glock 20 10mm and 5000 + in glock 21 45 auto and glock 19's 9mm

I'm actually going backwards - I love my 10mm, but I'm ready to purchase a 40 "short and weak" for running and gunnin
