Trying to help a buddy develop a load for his .47 cal RB twist barrel. .457 in every load and patch combo is mediocre at best. .470 and thin patch will work but loading tough in the field. Is there any chance somebody has some .465s hoarded away? I'm not even looking to buy alot....if you could sell me just a few to pattern the gun before ordering a custom .465 mold that would be a tremendous help ☹
