Went at this a little different, tried the Lee U die and Standard Lee Sizing die went back to the Standard Lee Sizing Die. Turn the powder through die down
till a piece of sized brass slips over the belling part of the powder through die. I used a drill press small files and sandpaper but it quicker if you know someone with a lathe.
Polish when through, might clean up the inside of the Powder through die a dremmel 1/8th drill bit with a strip of 400/600 sandpaper works well for this Polish
the inside with metal polish and a patch taped to the end of the bit.
Had a insert made, flat to put in the Lee seating die, helps keep OAL closer Dillon crimp die set with .0002 to .0004 crimp, If the Lee FCD is used back it off a bit so it only
crimps the very top of the case.
Lee's sizing die sizes closer to the case mouth and tighter than other brands. Because the carbide ring is closer to the case mouth set the come back after other dies
are set and set sizing die with a small strip of paper, should pull out with drag but not go in. If it hits the shell plate it can break the carbide ring.
Put your locking nut under the tool head as the threads are shorter on the Lee die. Use Dillon Lock nuts, lock the bottom with a good wrench, I put another nut on top
but don"t strip it out. The Lee Set is around $40.00 bucks. Be sure and Lube cases your working the brass harder. Loaded 500 nines last night with six that didn"t Drop all the
way in a Lyman Gauge, tighter than a Dillon.
