RE: Ballistics for 300 grain Hornady SST
I use a 300 grain T/C Shockwave (same bullet) with 2 Pyrodex pellets. Sighted in about 3 inches high at 100 yards puts me pretty much dead on at 150 yards. According to thesheet I have from Hornady:
300 gr SST has sec. density of .210, ballistic coefficient of .250.
With (2) 50 grain Pyrodex pellets here is what is listed:
