That’s exactly what happened, I took for granted as it’s usually a clean station with some quick ego boost for the rest of the round. I got sloppy and it got me. Probably would have been a dead bird with the 12 but not 410.
Another bad thing about the Bornaghi gold : I also had several FTF out of O/U. I noticed the primer is set pretty far down in the hull, haven't looked any further, but no more of these.
Not in the league of your reload. Not as even distribution and tighter. Having spent primers step out on extraction from the auto is a pain you can do without. Nothing worse to wreck your game or mindset when they end up inside even the odd one.
