40-70 Bullard
The 40-70 Bullard is one of a
small family of 40 caliber
cartridges made for the
Bullard Lever Action Rifle
introduced in 1887. The only
diffence in the 40-60, 40-70,
and 40 -75 Bullard
cartridges is the powder
charge amount and bullet
weight. Case neck diameter
is .413", which is a larger
diameter than most 40
calibers of that day.
