Below you’ll find several ballistics charts comparing the 450 Bushmaster to the 45-70 Government. The charts are broken down into subsections for manufacturers, and I try to get the bullet weigh as close as possible for comparison purposes. In many instances, I’m comparing the lowest weight to the lowest weight, even if one is significantly bigger than the other.
The 450 Bushmaster and 45-70 Government are two totally different cartridges and each serves different purposes.
