Awesome - thanks for the followup, loupav. It sounds like the issues might have been a bad ejector on one of the 870's, and dirty chambers on the others?

I'm a fan of his book "The Art of Modern Gunfighting", and have heard he's working on the follow-up. I hope he releases it soon.

I've got a pair of 870's, one with an Aimpoint and one with rifle sights. I'll have to take them out to the range next week, and see what I can do at those distances. Should be worth the time and effort.

Thanks again, and stay safe.
