So the internet and all, I read that full length sizing nickel rifle brass is a bad idea cause the nickel will flake off. I tried it anyway cause it was only 100 rounds, however all it takes is one to flake off. By the time I was done my shiny brass was all scratched up. Fast forward 3 months I bought a replacement set of dies and I think the chamber on my rifle must be really tight because after I full length sized them they wouldn't chamber. With nothing to lose I chucked up a bronze bore brush and wrapped a piece of greased up 1500 grit wet or dry and began polishing. I can still see some faint scratches but my rounds chamber. I'm assuming not all dies are created equal, anyone else run into this?
