I just started paper patching and was wondering what the story is on the off sized push through dies? I was looking for some undersized dies like .300″ or so to size down bullets for paper patch. Custom runs? One offs? Thank you!
For a .30 cal PB, check the .30 cal airgun bushings…. They go down to 0.298″…. same for .25 and .22 cal…. For some other sizes, check the next caliber below, sometimes you can find what you need….
