I want to shoot it over another chrony to see if it's any different than mine. I have suspected mine to be off from time to time but have never been able to verify it against another one. I'm kinda hoping LTLR will chime in on this one. He had a thread a few days ago shooting the 129 sst and made mention that the b.c. of that bullet was underrated. I would like to see how close his figures are to mine...
I believe they are both pretty close, but I also believe they are both underrated at .483.
To the OP, can you confirm that your velocity is correct?
That is the average across a wide velocity range
3000fps is .520
2500fps is .499
2000fps is .481
1500fps is .430
so i would guess that over 600 yards your bc calculation is spot on of .505
