Re: WINCHESTER BRASS ??
300 win have short necks to begin with but if it
bothers you trim them but try to keep at least
1 caliber in length (.308 min length)
These marks are from crimping and can be reloaded
So if you trim it off and its less than one caliber
you can ether remove .001 to .002 from the expander
plug (this makes the brass grip better)or use bullets
with a cannelure and crimp.
So you decide which way , but use it.
