Nickle Plated Sig Brass... What gives?

[Saluki91]

While loading some .380 on my Dillon 750 today, I ran into a snag with nickle plated Sig brass.

1 - It is super sticky on the powder funnel - much more so than anything else I loaded today.
2 - No amount of persuasion would seat the bullet deep enough. My target OAL is .980" (100gr plated bullets). Anything seated in the Sig brass would hit a wall at just under an inch... .997, .993, etc.

I realize that I could just scrap the Sig brass, but before I do, I'd like to make sure there isn't something I have missed.

Thanks for any insight you can provide!

Any chance the casings have a ''double'' wall that goes part way up? That could stop the bullet from being set where you want it.

Thanks for your response. I don't see a lip or ridge like I find on some 9mm cases.
