A little while back I asked Hodgon why they showed data for Super Performance in the 6.5 CM but not the .260. IIRC, they said they had an agreement with Hornady to not publish the data unless it provided 75fps velocity more with the same bullet than other propellants.

John

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
