Use ballistic calculator and keep adding bc value until calculator shows actual measured drop

That will get you close

You would think so eh
I have known drops all the way out to 805yards
When I use one of them (I think I used my 590yard dope)
And mv is known also
I added bc until it matched that number as you say
Came back with a bc of 0.750 lol I find it very hard to believe that a 334gn.375 round nose bullet has a .75 bc lol unless I’ve found the holy grail of bullets lol
Plus when I used that bc and tryed my other known dopes none of them matched they weren’t far off 4 or 5 moa though
