I would sell that too 

Thanks for the input. So far. i have loaded 100 rounds (all the new Starline brass I could find at first was a bag of 100 at Cabela's). The brown truck dropped a thousand more off two days ago.

I measured some of what i loaded so far and they measure .421" - .422", so I guess i am there.

I am using Dillon dies now, and have a Lee carbide FCD on the way.

i just wasn't sure how sensitive the 10mm was on crimp.

If I am using a powder like AA #9, do I need a particularly heavy crimp on 10mm rounds?

I know in 44 magnum loads, a heavy crimp is needed with #9 and similar powders to allow full ignition of the powder.

Should I be giving the crimp die an extra half turn or so down?

Thanks

I have never been a Glock guy and never owned one. But I have had an itch for trying out a 10mm for a while and the Glock seemed the easy, proven way to get started.

About the time I was getting serious about buying a 20, they announced the 40 and I put it on my "I will buy the first one I see available" list, which has been a pretty exclusive list. I don't think I have ever put a gun on that list ever before.

As luck would have it, I was in a LGS two weeks ago today and saw a used, as new 20SF on the shelf for a decent price. I looked it over and made a comment to the owner who shot me a smokin' 'out the door' price if I bought it right then and there. He does this now and then with the regulars just to see if your paying attention sometimes, and to his surprise I pulled cash out of my pocket and told him to wright it up.

I have so far shot some Hornady 180 grain critical defense through it. I liked it, but was expecting a bit more "shock and awe". I got a few boxes of Underwood in the mean time, and UPS dropped 1000 rounds of Starline brass on my porch yesterday, so I am going to be stuffing them with some AA #9 and XTP's later today to hopefully have some fun this weekend.

It has also accumulated some new sights (BattleHook night sights), a SS guide rod with a 22# Wolff spring, and a Storm Lake barrel. This is worse than a 1911 !

I don't know if I will buy a 40 when they hit the shelves now, will have to wait to handle one first.
