ok so I have tried making my battle rifle shoot out masterchief or warthog but every time I try and shoot the game freezes...can someone help me

 

Make sure that the master chief you are using is masterchief_mp, I believe. Otherwise, are those the only two things that you are trying mod?

 

have you had luck shotting anything els out of a br???

 

Ya, try to shoot something else, and see if that works, otherwise I wouldn't know what to tell ya.
