Hi

I am looking for a source which will give me some info on accurancy & trajectories of original loads for such as .44-40, .45-70.

I know they can pull in 2 to 3 inch groups at 100 yards and want to know what they can achieve at 200, 300 & 400. What a maximum effective range might be.

Are there any tables or books which would give this information for both rifles & pistols?

Thanks in advance.
