I am thinking about getting a 260 down the road, and was looking at ballistic coefficients of various 6.5 bullets out there. I came across the Swift Scirocco 2 130 gr, and they list the BC at .571. It seemed a little high to me and is far and beyond better than any other 6.5 hunting bullet out ther; for instance the 130 Accubond has a BC of .488 and the 140 gr SST is .520. Just out of curiosity I compared it to the 140 gr A Max which has a BC of .550. Is it possible that this is a typo or is it correct?
Swift Typo?

The 130 Berger is over .500 I know

The Berger 130 VLD has a B.C. of .595. The 140-grain VLD has a B.C. of .640. I've got a friend who has killed at least three deer over 500 yards with a .260 he built last summer. The farthest was 642 yards. I'm going to build a .260 before next season.

The 142 Sierra I shoot out of my 6.5/284`s has a B.C. of .595 which I consider correct. The other companies such as Berger will show very optomistic B.C. numbers. That rifle shoots really well in the breeze.
The .571 is probably right on the money with the Swift bullets.
My first custom rifle built in the 80`s was a 6.5/06 by looking the bullet values over in the Nosler Manual. There is something to it.
I picked out a bullet, and built a rifle around it.
That worked out so well, I just kept on doing just that.
The 7mm 140 grain Nosler has a better B.C. than a 165 grain 30 caliber. These are what I consider ideal hunting weights for the perspective bore size.
You push a 140 7mm close to 3700 fps and see how that works out for you.
