Is there any published information regarding what Winchester advertised the 45-75 did in the NWMP carbines? They must have told the NWMP what performance they were expected to get in the guns that they were buying. I have looked through the little reference material that I have and couldn't find any info on this.
If this info is available somewhere, we should at least be able to interpolate for the other calibers with some degree of accuracy.
A good project for all the researchers out there.
If it is out there I feel as though I must have overlooked it.
