7MM PRC compared to other 7MM’s

Is the 7mm PRC cartridge the ideal 7mm? Randy dispels the hype.
Randy tells why the claims are overblown. Please don’t cherry pick. Listen to the entire video, so you understand where he is coming from.
Randy mentions information from Hornady’s own site about how BC’s are variable and not consistent and this needs to be factored into any of the information.

The Ballistic Coefficient
Before discussing this topic in more detail, let's dispel some myths surrounding it. Whatever you may have heard before, these are the facts:
• There is no such thing as an absolute and invariable ballistic coefficient (B. C.)
• Ballistic coefficients are only one factor in bullet selection for different kinds of shooting.
• A ballistic coefficient can change with reference to (1) altitude, (2) temperature, (3) atmospheric pressure, and (4) relative humidity.
• Ballistic coefficients are measures of a bullet's relative efficiency.
• Ballistic coefficients are not measures of a bullet's "goodness."
• Higher B.C.s do not necessarily make a bullet "better."
• Lower B.C.s do not necessarily make a bullet "worse."
