I don't know the BC, however, the front end measures about 320.  Fatter than an LFN but narrower than a WFN.  Mine drops out the mold about 431.5 and weighs about 313 with a check.  If you fiddle with the mold (Lap the top and sprue flat) not a bad bullet for the price.  21.5 grns 296, WWLPP and starline brass gives 1350 fps out of 7.5 inch SRH.

B.C. ought to run about .2 or so.  Just compare to the closest weight jacketed with a similar profile (which is probably the Sierra 300 gr., Speer 300 gr, or Hornady 300 gr. - you could probably just average the 3 and be close enough!).  Don't get too hung up in BC numbers, they can vary quite a bit from gun to gun and even when the loads are tweaked a bit, as sometimes the bullets don't stablize as easily under different circumstances and this can increase the drag quite a bit.

This should get you close, and if you want to figure out your sights for long-range shooting, try them out and see what the actual results are.
