First it is a boat tail design, totally worthless in the hunting field.
1. 95% the deer I've killed in the last decade would dispute that, if they could ...but they can't: they are dead.
2. If you want penetration (ELK!), then don't use a standard lead core and jacket bullet. Nosler Accubonds, Hornady Interbond, Swift Scirrocco,etc, etc, will give you the high BC of the boat tail design, and the jacket and core won't separate...... right tool for the right job, McFly.
