Bullet types & Designs

So thought I’d start this thread. There are a lot of designs & constructions out there some very cheap (cast) and some fairly expensive (partitions) I have been using Hornady interlocks for some years and I don’t get out often but everything I’ve hit with them has pretty much been a bang flop. There price doesn’t hurt the wallet too much either. Here is a shot off a promotional video. I have sectioned a couple and this image is fairly accurate.
