The “bottle necking” looks like a gun problem not an ammo problem. Do factory rounds do the same thing?
The cases will likely be OK to load after sizing and expanding the case mouth. The 9mm is not a straight walled case it is a tapered case.
Thanks for the reply.

I measured the cases before resizing given the difference in their appearance from the ones fired thru the Sig. Maybe the PPQ and P30 simply have larger chambers while the Sig's is tighter.

I will take some factory ammo with me the next time I head to the range and save the cases. From what I remember, fired factory cases looked 'normal' from both the PPQ/P30 but it bears confirmation. I'm enjoying the hobby and appreciate the assistance as I go thru the learning curve.

Have a great Labor Day weekend!

Cheers!
