[QUOTE="Kevin Thomas, post: 590460, member: 15748"] Okay, if it has appeared in the factory ammo, I think that was probably the cause. If it appeared in the component brass, is there a chance you're crimping it when loading? Most standard seating dies incorporate a crimp feature. Most of us simply bypass this (it's not needed in about 99% of reloading) by adjusting the die upwards to where it seats without the crimp engaging the case mouth. If you weren't aware of this, you could have very easily been crimping without even knowing you were doing so. Either way, if you adujst the die up to where it's not crimping (refer to the dies instructions on how to back them off to avoid this) and just size normally, I'm guessing this will disappear after another firing or two.
