Oversize .45 Primers

[Delkal]

I don't want to Hijack a thread (I think it was answered anyway)...... But I just finished sorting thru my reloading bench trash can and I found the "stepped" 9mm cases. The headstamp is Ammoload.

I can't post a picture since I cancelled my Photobucket account but here is a link to a post about them. There is a picture there.

Small, Large, Large. Optical illusion due to silver vs brass color at right, and all brass at center.

With the hi-res photos (which are better than my eyes) I will agree with you, and add a bit more:

Red is where primer meets case
Green is where pocket starts depressing from base
Yellow (left) indicates taperedchamfered base of primer
Blue (right) indicates debossed area around primer, which is itself square-cornered

So, the flat of the primer is larger on the right, and the case has a flat section around that before tapering up to the headstamp. The headstamp area on the right is narrower from primer to edge, leading to the illusion.

It's just an illusion.

I'm familiar with cannelured cases, but that's the first I ever heard of a step! More detail would be appreciated!

Have heard since then it has more to do with their manufacturing process of seating the bullets.
Dunno, but all cautions applicable.
