I suspect the profile with the step between the truncated cone and the driving band section is what will be the difficult bit, it might require something to be firmly grabbing the case and pill and go from there.

I'm going to have to disagree on the depth of the hollow point. I spent a bit of time yesterday playing around with the really long narrow hollowpoint that I was getting inconsistent results with and found that by adding a small 45degree flair to the nose of the HP, I got excellent expansion on all 5 rounds I tested. The projectile expanded up to around 0.460" and the mushroom curled all the way past the base of the projectile, so the whole thing was maybe 4mm thick. Unfortunately I forgot to take photos and am now at work.

The downside to this deep hollow point is that it works the projectile a lot and I'm finding not all brands can handle it, so a smaller hollow point with a little less expansion is probably more practical in the real world.
