Hello,
I recently purchased an 1898 Springfield. The guy I got it from said after he slugged the barrel, he determined the bore to be at .310. He used 311. bullets to get the best accuracy. I want to reload for the rifle but just want to neck size to get the most out of the brass. Would it be possible to use a neck sizing die for a .303 British caliber to get the proper neck diameter for .311 Bullets? Thanks
