Hey Danny, no the beef injection would be different as would be the brine. I use SuperDave's recipe for the beef injection. The recipe is 1 can of beef broth, 1 tbl garlic powder, 1 tea better than bouillon, 1/2 tea worcestershire sauce. As for doing the 7# flat no just use a therm. and look for an internal temp of 190. Good luck. Make sure to use a water pan.
