I keep hearing that Winchester only produces 7x57 brass on a "seasonal run". Does anyone here have a clue as to when that might be? Is that yearly, every-other year, once a decade..... Everyone gripes about Remington brass quality, Norma is too soft and too costly, PPU can have issues, no Lapua available, no RWS that I can find, Federal brass is too soft, reforming is a hassle. Maybe I should just sell my 7x57 shocked .
