I was thinking of getting a BDC type scope for my Ultra Slug with just 2 or 3 holdover lines/dots. I'd like to sight it in with the center duplex hitting at 100 yards. I was thinking of then shooting at the same 100 yards using the holdover lines so they should incrementally each hit higher on the target. I could input the bullet weight and velocity into a ballistics chart and keep adjusting the "zero yardage range" until the inches high at 100 yards lines up.

I'm not interested in finding a load to match the BDC, I just want to know what the yardage is for each line with the ammo I choose. Will this work or is there a better/different way? Thanks.
