Ya'll would laugh at my experience at shooting beyond 300 but I made this tape last year after choosing a hunting load for my 300WSM. I used the average velocity for the 180 DC's and it was right on a 325 and 500 but off a bit at 700.
Now I just need room to practice!
RDW, I'm loving the hell out of your yardage tape as well. My Zeiss 3.5-10 is also lacking in the turret department. I like what you did there. You could make money selling those
BSA, I am not sure I could sell one turret tape but I could sell the chit outta MOA printed index cards
