Since lead is a very dense material, bullets made of inexpensive, non-toxic materials will be lighter than bullets made of lead unless bullet length is increased. Inferior external ballistics cause lighter bullets to be less effective against distant targets. Increasing bullet length may require a faster rifling twist to maintain stability.
The size of the lead shot that is produced is determined by the diameter of the orifice used to drip the lead, ranging from approximately 0.018 inches (0.46 mm) for #9 lead shot to about 0.025 inches (0.64 mm) for #6 or #7.0 shot, while also depending on the specific lead alloy that is used.

However, at speeds greater than 300 m/s (980 ft/s), pure lead will melt more and deposit fouling in rifled bores at an ever-increasing rate.
