So I learned this weekend that a letter 'N' size drill measures about 0.302 inches. That's just about the perfect diameter for a smooth side paper patch boolit to shoot in .30 caliber rifles.
So here's the plan: the next time I order reloading stuff I'm going to pick up a Lee 7mm rifle mold. Then I'm going to clamp the blocks together and drill the cavities almost to the nose with a N bit. Hopefully I can get a decent transition at the nose with the existing cavity. Then I'll cast some up, patch them and let 'em fly!
That's the plan anyway...a poor man's PP .30 cal boolit. Anybody like this idea better than just casting .309's and squeezing them unmercifully after they have been patched?
