ballistic coefficient questions . 6.5 mm bullets

So since getting my 6.5 Creedmoor I've been studying the bullets that hopefully will work best for my purposes.
When checking the BC of many bullets I found what appears to be a misprint. But since I'm not to good at math I am hoping someone who understands this could explain it. .the 2 bullets in question are the 140 gr Hornady SST and the 130 gr Sirrocco II.
the SST has a BC of 520 and the Swift's BC is 571 .
The SST is longer than the Swift and appears to be more streamlined. What is the cause of the. 05 difference.

Thanks in abvance.

Swift has grossly inflated their BC's for years. You will find if you shot them at yardage they are not even close to as advertised.

OK, so would the real world BC of the Sirrocco bullet be similar to the 130 gr AccuBond. ??

I can't answer that as I have no experience w the accubond. I'm not a Nosler fan at all. Sorry I'm no help on this.

No, I really appreciate it. I got a box of the Swifts because they had such a high BC listed. When camparing them side by side with the 140 SST they werent anything to write home about. .

I see Nosler is making the 140 gr AB

You really owe it to yourself to try the 140 Berger in a 6.5, it's BC is nuts on and the performance is hard to beat, my dad's been through a lot of bullets in his 6.5 Sherman and just keeps coming back around to the 140 Berger.
