Range Report 308 175 rdf bc?

[Gil P.]

Does anyone have data on it's BC? I'll test the drop at distance when I get some anyway, just want to see if it lined up close to what I get.
I want to switch to the RDFs from the SMKs. Much cheaper.

i ran 500 thru a 1:12 twist...going 2675 fps i had to drop the advertised BC to .505-510 iirc...confirmed it out to 1180 yds...from a 1:10 or going faster, that might bump up a little

Thanks! Do you recall your atmospheric data?
