i made 3 up this morning. here is a pic. i'm gonna shoot 'em this afternoon.
it looks as though the shoulder doesn't have as sharp of an angle as factory made cases, but i'm sure after one firing you could never tell. i got a little dent on once case. neck thickness seems very close to the 338 rum.
left, factory 300 rum. middle, 300 rum sized to 338 rum, not trimmed yet. right, original 338 rum.
Worked for me just fine too.Worked fine. I used a regular die. This was when brass was hard to get.

there is some for sale in reloading supplies names grouseIm in the process of building a 338 Rum. The problem I have is brass availablility. No one seems to have any in stock at this moment. Can a person form it from 300 Rum or 375 Rum brass. Is it feasable to push the shoulder back .01 without any problems. Has anybody tried this before? any help appreciated.
