I shoot reloads and I have very few bad shells, maybe one in every 400 shots. I load the shells for about half of what they sell for new. I use high quality shot (Lawrence magnum) and I am constantly checking the powder charge, every 10 to 15 shells. I can't see what the manufactorers could possibly use to make their shells perform better. Reloading takes very little time, I'm wondering why more shooters don't reload. You can easily customize the load to what ever you want.
