[QUOTE="woods, post: 518503, member: 6042"] 4D makes a reamer that a smith can rent for a 30/375 Ruger [url=http://4-dproducts.com/display.php?group=Rifle+Calibers]4-D Products Rentals[/url] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/30_375_Ruger.jpg[/IMG] you gain about 6 or 7 grains over the 300 win mag but in an unbelted case.
