Here we explain briefly the various categories or types of bullets we make. Bulldozer (BD-2) & Super Bulldozers (SBD-2): These bullets are expanding high BC bullets intended for hunting. They are the second generation, sporting a proprietary ogival shape that not only improves BC over the first generaion Bulldozers, but also lowers expansion velocity to…

This section will be devoted to discussing those factors which influence bullet penetration through animals and the importance of bullet spin rate (RPM). The discussion applies only to expanding bullets. In an animal, there are different tissues which are of differing densities and hardness. The frontal skull bone is typically the densest and hardest, and…

The combination of BC, reliable, expansion and extreme penetration make the Bulldozer 2 bullet line of hunting bullets the most effective hunting bullet in each caliber and weight category available. We get many questions about how to reload these bullets safely. This article addresses many of the most common questions. _*What twist to use. *_For…

The definition of sectional density is mass divided by cross sectional area (M/A).  As it applies to bullets it is the weight of the bullet in grains divided by 7000 times the diameter of the bullet (Cal) squared M (grains)/7000 X (Cal)2 Sectional density alone in, general terms, predicts penetrating ability of the bullet but…
