Thread: Cast bullet BCs

The bc’s are not very accurate
I know my dope out to 800y with my 45/70 with the 500gn lee with 61gn by waight of 2f swiss Black powder in moa just from trial and error once you know the sight settings for 2 known distances you can then easily calculate where you should be at any said distance i can normally hit 1st or 2nd shot just from a simple calculation used by the old timers

I also know my Velocities and everything needed to do a modern drop chat me and several of the other guys tried it and its not even in the ball park for our bpcr rifles.... yet we use the same chats to shoot our modern rifles to that and farther with very little trial and error
