dram equivalent

The amount of powder in a shotgun round. A higher number means more powder, more pressure, higher velocity, and sharper recoil. Loads designed for hunting have higher dram equivalents (3.25 or more), while target shooting loads have lower ones (3 or less). Magnums can reach 4 or more.

Two seemingly identical loads do not have equal recoil. That is because of dram equivalent.
