Bumping up

[Pistol Champ]

I have a lot of sized and lubed lead bullets that are 0.313" dia. I would like to get them bumped up to 0.314 does any one know of a simple fast way to do a large volume?

It would depend on the shape of the boolit. If it requires a top punch to keep from deforming the boolit, it will have to be done one at at time. If it is a flat nosed design, perhaps between two steel plates in an arbor press. The only way to get exactly the size you want is to bump them to over sized and size them back down.

Get a .314 sizer die, stick it the sizer with the proper TP and experiment on how far you have to pull the handle and block it there. That will only work if the alloy is soft enough to deform easily. You can break the lubrisizer doing this. If the alloy is too hard, you're outta luck.

I had about 15lbs that I put back in the melt they were about .007 too small.I think now that I maybe should have experimented with some paper patching.
