Comparing The Big Bores

Bullet comparisons:

Note: All bullets are Barnes Solids in order to keep nose shapes and long for caliber comparisons between calibers equal for penetration tests. The 450 Ackley was not able to reach full velocity with the Barnes Solids so Hornady Solids were substituted. The .510- 600 grain solids are A-Square monolithics which have the same characteristics as the Barnes solids.
