[QUOTE="waskow54, post: 827622, member: 62968"] There are a number of manufacturers who make .338 Win brass. Making it from .300 Win brass seems a little difficult. Winchester was a little late with the .300 Winchester. Norma necked the .338 Win down before Winchester did so they moved the shoulder forward by about .1" to make the .300 Winchester. Necking it up to .338 Win would involve pushing the shoulder back. I think you may be able to do it with 7mm Remington mag brass. Check the length from the base to the shoulder to see if it's the same length before trying it and then only if you can't get .338 Win brass. Maybe use a .30 diameter sizing ball for the first pass then go to the .338 sizing ball. I would only do this if I couldn't get factory .338 Win brass though. I've had good luck in my Nikko Golden Eagle .338 Win with Winchester cases. I've gotten six or seven reloads out of these casings and the Nikko is a rear locking bolt action. [/QUOTE]
