[QUOTE="sewwhat89, post: 81893, member: 4587"] I am not getting anywhere close to the ballistic tables some of you guys are listing with published bc values at STP. How can I go about calculating my own bc? I know the ballistics for my 300 SAUM shooting 178 gr AMAX (.495 bc)and 175 gr SMK (.505 bc). The AMAX shoots flatter at 500m by about 4 inches. The muzzle velocities are the exact same. Is the AMAX bc low or the SMK high? Thanks! With 100 yd zero: 175 gr SMK 43 clicks to 535 yd zero 178 gr AMAX 40 clicks to 535 yd zero [/QUOTE]
