More formulas and paper ballistics to throw out at everyone. I ran the numbers on Taylor Knock Out and Thornily Relative Stopping Power just to see where everything stacked up. I was intrigued to find the 30-30 and 35 Rem stacked so much lower and would attribute that mainly to the mass the other rounds are carrying.
Could someone let me know if there's any sort of scale Taylor's formula can be compared to just to obtain some more insight on the information there?
I went to Buffalo Bore's site to get the information for a comparisons I've listed below for everyone to look through. I think we can all agree Mr Sundles is pretty straightforward with claimed ballistics and doesn't embellish as other companies are known to do. In my experience they usually give a little bit better velocity than he advertises.
