9mm processed brass question

[rockwind1]

i've never loaded 9mm before. getting ready to use my new dillon rl1100. i picked up alot of once fired mixed headstamp brass from one of the usual places that takes range brass and processes it thru a big dillon machine,,, in fact it was sized twice in the processing. i've loaded for my precision rifles. pistol is a little bit of a new thing for me. my question

i was looking at the brass with the naked eye and it kind of has a "nuclear cooling tower" shape just barely so i of course measure it with my digital calipers,, the base measure .388, then in the middle it is about .377 and is maybe .374 at the mouth actually

the length is .749

i just don't know if that is about what it should be,, would someone out there be willing to measure their processed 9mm and let me know what it measure at base, middle and top? thanks if so.

That's normal, especially with Dillon dies if thats what they used. 9mm is a tapered case. Chamber an empty piece of brass, if it fits load up.

Pull the barrel and drop in a couple of your loaded rounds to make sure there good before you load up a bunch.... It's alot easier to pull a few bullets than a thousand.... If you do a search on here you will even find pictures of loaded 9mm and what it should look like... As stated above that look is pretty common with Dillon dies...All your length data is in your manuals.... It's important on 9mm that your over all length be correct , the deeper the bullet is seated the higher the pressure...
