I'll try a .308 bullet to 'patch up' first.
Then I'll compare that to a slick sided bullet with a modified Lee mold. The Lee mold is $21 online and it comes predrilled with its 2 cavities.
With 2 cavities I could experiment with different diameters and weights.
At this point I wouldnt care if the nose looked like the end of a drill bit, I'm looking for something to stabilize and relatively easy to load.
Anyway, I could control the drilling depth and leave the original Lee nose profile intact, maybe the end result would have a shoulder like a semi-wadcutter.
