Is this issue also occurring out of 20" barrels?

Maybe I don't understand your question.

Overcharged is overcharged whether it's 16 or 20. The velocity numbers are just bigger on the 20 like they always are.

Or are you asking if swipe marks are still seen on 20 bbls? Markm was seeing marks out of his 20 and I believe others reported same.

Yep. 20 inch is what I chrono everything with for comparability. The swipes and high velocity were why I stopped shooting the ammo after 5 rounds.

Yes, that was my question. Both you and markm have answered it.

Last weekend I was shooting that Independence 55gr ammo out of my BCM and I had a primer blow and the case got stuck in the chamber. I will not be buying it again. Downside is that I got an ammo can with a mix variety of 55gr ball, and there is Independence cartridges mixed in there as well.

It has an FC head stamp. Should be easy to pick out.

Yeah. The Indy headstamps aren't hard to spot.
