When you say side by side testing what do you mean? How many groups of how many shots each? Tighter by how much? Same loads with bullets same distance from the lands?


I have not shot the NBT in more than a few years from my 30-06. Used them religiously at one time and accuracy was great found them more destructive than any. Is your experience better today than say 10 or so years ago? I would go back I think there's not a lot of difference in the 2. Don't really know that it merits much consideration.

When were talking 1" and 1.25" that's not much they're probably shooting to the same hole. I would not think their ogive or boat tail are dissimilar at all.

Good luck and shoot straight
