Most of the Corbon stuff presents amazing results when fired in to ballistic gelatin. However, the lighter weight bullet than average, the thinner than average jacket, and the higher than average velocities do lend to the bullet not being able to penetrate as well when there are mediums between the gun and the target. If the Corbon needs to defeat glass, heavy winter clothing, or other such common mediums found in every day life there is a high probability that the target will receive a bunch of shrapnel instead of a slug, according to the multiple studies I've seen. Corbon ammo is great stuff and produced amazing wound channels when tested directly on ballistic gelatin, but it fell behind when tested against mediums. Just be mindful of that.
I simple use a good HP with a known record of success. The Hyrda-Shoks and Gold Dots seem to lead the way. There are many others that will work well. The Silver Tip and Golden Sabre are good too.
