I was wondering how some of the more experienced out there makes their point form dies . Is there any formula for making the ogive like a measurement formula or do you just turn a piece of steel/aluminum or brass/copper on a lathe , file it down , measuring until it looks close to make a reamer ? What material works best if the dies are made from A2 steel ,which I'm planning on using ,maybe O1 ?
Also wondering how to lap these . I've got acro laps blind hole laps w/ spare barrels and they appears to be great for the straight thru part of hole but how to get the ogive and bullet face ? I read where one memeber uses a correctly sized ,swaged piece of lead and another drills a jacketed bullet using it on a post chucked up in the lathe . Then I plan to use diamond paste in decreasing sizes . I hadn't really found a source for custom diameter laps anywhere ,so looking for some ideas that will work and I don't happen to have a sunnen honing machine , but wish I did for times like these . Just started collecting metal working equipment and have a little more then basics for now but really interested in trying to make some of my own dies and other equipment for Swaging . I've got plenty of time and think it makes a great hobby while gaining items I will keep and use for a lifetime ,if I can figure out the smal, details - thanks for any advise guys !
