If you guys want them to load easier??? The next time you have your breech plug out of your rifle, push one of the bullets into your bore upside down (you will be pushing into the hollow cavity of the base) far enough to swadge the rifling kerfs into the base, then either push it all the way through or push it back out the muzzle from the breech end. The majority of the bullets length has a diameter of only .497", that will fit in any .50 caliber, it is only approximately the last .125" of the hollow base that is flared out to .507". Now simply align the bullets rifling kerfs in the base with your rifling in your barrel right-side-up, now tell me how easy they load?
If you like the results, push your whole pack of bullets through in the same manner. The next time you go to the range they will all be pre-rifled for easy loading. Just remember if you are using different rifles, the rifling diameter and width of lands and grooves will be different from a different make, like a T/C and a Knight for instance.
Try it, you may like it.
