Picked up a Walnut Hill press, and a set of dies for use in a reloading press made by D.R. Corbin. This was last summer. I have not done anything with the Walnut Hill press, except using it to trim rf brass to length. The dies are for .224 bullets, There was no info. on the ogive dimensions, or what jacket they would work best with, but look like 6s. I believe they were intended for use with rf jackets, as a rf jacket maker was in the set. But regardless, of what I have tried, I can never achieve .224 dia. bullets. The cases are tumbled with ss pins, dried, de-rimmed, and then annealed. Cores are cut from wire, formed, de-greased, core seated. Now here is where I run into problems. When I seat, I cannot get over .223 dia. even when exerting enough pressure to move lead past the core seating punch. And of course, I do not get any more diameter when point forming.
When I use just a core in the core seat die, all I get is .223, so jacket springback is not the trouble. The dies are marked .224. Also I have tapered bullets, within .125 from the base, I only have .222 dia. I have an old die made by Herter's Inc. it is easy to get .224 with it, although it has a home made nose punch, and not with excessive force either.
The bullets have so much taper, when I seat them in a case, and the base gets below the neck, the bullet falls inside. I tried to make 70 gr. from 17HMR cases thinking the longer bullet would offer more resistance in the die, but not so it is the same, undersize and tapered.
So here I am asking for direction to get me on the correct road. I waited, and read, and read some more, so as not to bother anyone prematurely, but now is the time for advise.
Thanking everyone in advance;
