Well, no, thats not what I was saying. The problem is not that the bullet goes transonic, the problem is that the design of the bullet causes instability when it goes transonic. The other two bullets are a different design and probably (I do not know for sure) do not suffer the same problem. There is usually no problems with bullets going transonic and then subsonic, its usually not that big of a deal.Kiwi said:are you therefore saying Hornady 168gr and Lapua 167gr will stay super sonic further out than Sierra 168gr? and if so, how much further?
