The only issue with .358” bullets is with Winchester brass. The neck thickness is .013” but with stat line brass it is .011”. I reload speer 180 hotcors that I run through a lee .356” sizing die and have zero chambering issues in my x-caliber barrel. I also load fury 180s and they shoot less than half MOA out to 350 yards at an average of 2365fps. It is a fun and very accurate cartridge.
