thanks griz!
are you talking about the overall length of the round itself, or how it fits in the box?
the green box has an internal tray that can be rotated to accommodate long or short rounds, whichever the need. i don't really like the green boxes, they take up too much room. i am partial to the cheapo plastic boxes from midway or berry's. i just happened to have the green MTM boxes so i use 'em. they were left over from my silhouette (sp?) days. they were just the ticket for silhouette (sp?).
the overall length of the round is determined by the crimping groove on my cast bullets. as long as i crimp them in the crimping groove, no problems.
