Ballistic tips are good bullets, but they're not boattails so their BCs aren't up there with the A-max or Berger vlds.

It's all about the wind when you get out there, and BC affects the amount of drift.

Get a ballistics program or go on Berger's website and use their ballistics calculator to enter in different BCs and see how wind drift is affected at long range, that will give you a good idea of why bullet selection is important.


Excuse me, but Nosler Ballistic Tips are indeed "boatail" bullets anyone can see that.


A ballistic tip is not a true boattail bullet. They're not flat-base, but their "boattail" is inconsequential compared to a true boattail and it shows up in the BC. Here's a photo of three 6.5 bullets, with a vld on the left, a 120 grain BT in the middle, and a 123 grain Scenar on the right. The vld and scenar are true boattail bullets:

The G1 BC of the 123 scenar is .527, and the figure given by Nosler for the BT is .458. Brian Litz has the 120 BT pegged at .418. A lot of the difference is due to the BT's lack of a true boattail.



A wise man is frequently humbled.
