Re: Static vs Dynamic BC for bullets
[ QUOTE ]
BC and drop numbers derived from these methods typically put the paper data to shame. Most folks don't realize that bullets have different BC's for different velocities which is why I think most published data just ain't quite correct.

Thats a fact!!
I have used some bullets and found them to be quite close to the published BC and other WAAAAAAAY off the mark. No pun intended.
Very true about differant BC's at differant veloities. They also can change with barrel twist, load density, barrel length and I am sure a whole lot more. I love the example of my 178 AMAX tests which out of an 11.25 twist 308 at 2550 FPS the REAL world BC was .318 on the G5 model and out of my 12x 300 RUM .495 on the G7 model which is VERY close to 1.015 on the G1 curve! Thats a HUGE differance.
There is more to BC's than most would think.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.
