Thank you all for the insight. I do like the .45-70 for what it is, but I still believe it's performance can be altered some. For instance, the 250 grain "X" bullet will shoot much flatter than say a 405 sp, and this is what I was getting at. Most of my shots will be within 70 yards, but it would be nice to know that I can hold dead on out to 130-140, rather than having to hold high if a shot is presented at that range. As far as I know, the 250 grain "X" is still a flat point, but that will probably work fine for whitetails. .Just looking for suggestions and opinions and that's what I got. It is really cool to have access to so much experience and knowledge. Thank you all. :-)
