tex-n-cal Yes, yes, and yes to everything you said. My 9mm's look like the proverbial snake swallowing a frog (on purpose).

I FIRMLY believe that a HIGH percentage of "overloads", "blown" cases, etc. in auto loaders are due to the bullet being seated deeper by the rather violent feeding of the round.

I read a test done years ago with the 9mm (think it was in "NRA Handloaders Guide") . A few 1/1,000 deeper seating took the load from 30,000 cup to 65,000 cup. You can imagine if the bullet was set back until the compressed powder charge stops it. BOOM !!!!!

If your dies won't or can't size enough to at least get a bit of this effect, CHANGE them. It is a problem considering variations in brass thickness.
