Thread: can someone work out my max point blank zero

ive done it myself. I just want to do the idiot check, as the numbers don't seem quite right

my load is a .284 162gn edlx doing 2840fps distance to crony 0 (lab radar)

I set the vital zone radius at 5"

its saying Zero distance should be 273m
And MPBR should be 0-323m

Can someone double check please

im useing JBM
