What's Your Go-To Powder and Primer for 280AI?

[Sennaspeed]

64gr of Magpro and the WLRM push the 162Amax to 3050 with my 26" barrel.

Love Magpro.

Nosler brass, 210M, and h4831sc push every bullet I've tried half moa or better in mine.

I need to check my gun is pretty new but I want to say I'm shooting H4831 with 150 barnes TSX. I do know that a 4 shot group is .392.
