Hi all, just a quick one: bought two factory boxes of 44 mag from Federal. I usually get Hornady XTP, which stock would rotate heavily from my LGS. They always look the same, consistent quality amongst the cartridges.

I'm wanting to know how the brass has discoloured like this, differently amongst cartridges in the same box, and what causes it? It's strange to see these factory boxes with one discoloured case next to a pristine one. The ammo is fine, I'm not fussed and I once I tumble the cases and reload them they'll all look the same - I understand that environment and humidity changes brass, etc, but why doesn't it happen consistently amongst the cartridges in the same box (produced, I assume, at the sane time at the Federal factory)?

Not trying to promote the company, but has anyone heard of or been to this one before? Been wanting to do some hunting classes to learn the ropes, I don’t mind going at it a few days back to back if needed, but the only place I could find in NSW near Newcastle so far.

I bought a second hand Adler A110 that came with a Lucky 13 remington 870 forend adapter. For the life of me I can't separate the barrel from the receiver, it will not budge any further no matter how hard I run the lever and pull.

So im just wondering if anyone would have any insight or suggestions, I dont know if it has something to do with the forend adapter since I cant find any manual online.
