I have the same caliber in a T/C Contender barrel. Working on loads for it now. I’m getting the best accuracy with H-4350 and N140 with a 120 gr Nosler Ballistic tip. Average velocity is around 2300. Fire forming the brass isn’t too bad of a chore. I use 9 gr of Unique and cream of wheat to form mine. Works very well.
Good luck with yours.
