I guess I should have been more clear. "Round" wasn't the correct term. I use full length sized piece of brass . Which is the method I learned on this forum 15 years ago. Some feel it's safe some don't . I personally have never had any issues doing it this way. I greatly appreciate every criticism and comments I receive on this forum from all members. I've only done 5 builds in those 15 years and have learned lots along the way and still have more to learn I know .
