I shoot the 140 C/T bullets & over max loads of IMR 7828 in Winchester 7 STW brass or Fireformed 300 Weatherby to 7 STW. Only the C/T bullets will get this speed, go to the same bullet in 140g Ballistic tip and max load is much less due to pressure issues.

My "graph" is a Ohler 35P and a Pact Professional with Ohler Screens.

Bob Sutton was the name of the gunsmith in Dalton, Ga that was building these 6.5 wild cats.
