1. The shallowest penetration is achieved with a hemisphereical round nose solid, like a Barnes solid, a TCCI or an A-Square product.
2. Next shallowest penetration is achieved with a more sloping round nose, like a Woodleigh solid.
3. Second best penetration is obtained from a flat nosed solid. Examples include Bridger, GS Custom FN solids, Speer AGS and Trophy Bonded Sledgehammer.
4. Best penetration is obtained when a supercavitation disk is used, found on the Norbert Superpenetrator.
That being said, getting flat nosed solids to feed properly is a little more difficult than getting round noses to feed, but worth the effort. least
