Just a little tip here for those who use a single press, meaning not something like a Dillon, for reloading cast bullets.
When loading cast bullets we have to expand, or bell, the case mouth a bit in order to keep from shaving lead off the bullet as it is seated. We want to make this belling of the case as little as we can, to preserve case life.
A gas checked bullet requires less of an expanded mouth than does a flat base, because the copper cap is a bit rounded on the base. The flat base bullet usually has a sharp shoulder, which tends to grab the lead, unless there is sufficient belling of the case.
However, a simple operation is to place the base of the bullet into a chamfering and neck smoothing tool, as used on the case after trimming. I have the Lee and a 45-70 bullet just nicely slides into it, butt first. A couple of turns will relieve the sharp corner on the base of the bullet.
It will now smoothly load into the case with no more belling than is required for a gas check bullet.
