I shot a bunch of 3.5" Hevimetal on a spring snow goose trip in Lancaster County PA... absolute garbage. About every 7th shell failed to cycle. My SBE2 is in perfect condition. Pulled the backup, an SBE1; same thing. Took a hard look at the shells and about 3 per box were crooked, with a rolled over kink about halfway down the shell. I'll never buy another box, much less a case.
