Since nobody has replied to this, I'll throw in a couple thoughts. First, I'm going to assume you are looking to swage jacketed bullets since you are asking about boattail bullets. I've never seen a boatail cast lead bullet, but some do swage cast lead bullets.

Typical boatail bullets have a taper at the base of the shank then a flat on the bottom. The degree of taper, length of taper varies between die makers. The only rebated boatail bullet I've seen has a step of sorts at the shank, then a small boatail. Rebated BTs must not have caught on much cause not many make them.

Makpeter, 4and1 is right that these are generally used with jacketed bullets. I made a little drawing to show you what the differences are. I believe that most swaging tools are the rebated boat tail because there is more material in the die and less likely to expand and get hung up. I have a Corbin Walnut Hill that I make jacketed .228" diameter rebated boat tails with and they are very accurate. I don't have any experience with swaging plain lead with this base shape so I cannot help beyond this. Thanks and good luck, Squid Boy
