Hey guys,
I am looking to rebarrell a 338XTREME, I would like to get some dimensions on a 338Cheytec improved. Anyone have info to share on this cartridge?

2nd question, I have 500 pcs of the 338XTREME brass, I would like to be able to use this in my next barrel. This is why I’m thinking the 338CT Imp. Or would it be possible to use it in a 375IMP. ?
