FMJ yaw and upset performance

[stanc]

Thanks for the links, Joe. The next question is obviously - to what degree can these BCs be replicated in a mass-production military ball round?

The only published figure readily available is that for the Norma 120gr FMJ (BC=0.428), which -- since it's roughly the same as the BC of M80 Ball -- seems inadequate to achieve the desired ballistics.

If only the mythical Wolf 110gr FMJ had materialized, we could've had more data to go on. As it is, people -- including myself -- have been doing a lot of guessing at a possible BC by looking at other bullet types (HPBT, solid, Accubond, etc), which hasn't given a definitive answer.

The only other option I can think of is if one could find out the BC of the Swedish military AP projectile, which weighs 7.3 grams (113 grains?). Nicely streamlined, but likely doesn't have early yaw in soft tissue simulant.
