Jim, no disrespect intended - point-blank isn't as easy as the math makes it appear!
A [roughly] 1/2 "MOA" ten-ring, remains ample, but, difficult: the X-dot, at 300 Yd. (3/16") is, even with a decent ZERO and dope, just luck. Perhaps you have already demonstrated the apparent advantage of HIGH BC bullets at "close range" - if so, forgive my ignorance.
When, throughout the 2013 1nd 2014 seasons, I set out to capitalize on .500+ BC, at NBRSA registered 1/2/300 Yd. events, all I could muster was a, "wash": I won some, and lost some. In those where i doped well enough to win/place/show, using the 500+ BC bullets, I' d have posted equal scores using the more traditional - .32-.34 BC - bullets!
A good read and good execution shot a ten, or, X. A not so good dope - as in, "it'll go" - shot a nine. The shooters on either side of me, on their misses, generally, shot uglier nines, . . . the score keeper didn't distinguish between a good nine and a poor nine!
I do not know an individual who can accurately identify the wind velocity, but plenty, who, with flags/mirage, can identify a specific condition -
"there it is" - and execute a good shot. Regardless of BC, at P-B benchrest tournaments, the latter individuals consistently win/place/show. In my experience, LR and P-B have proven to be different animals.
The BIG lesson: there's a
BIG difference between, "
it'll go", and, "
there it is"!
