Although I have not started reloading yet .I have been doing some reading on the subject . I agree that you might want to move this thread to the reloading area of this forum . Dirty bullets may not just be dirty and that "dirt" can be an indicator of a bigger problem with the ammo . You should post some pictures of more then just one of the bullets that gives a good representation of the lot .
