Thread: .223 77 grain TMK

BM2 is Benchmark in the US. I use 23.0 as a generic load and it does well with 75-77gr in all of my bolt guns and ARs. I haven’t seen XBR 8208 on the shelves here in years and, if I remember correctly, I was using 24.5 with 75-77gr bullets.

24.0 of BM2 gave me 3000fps from a 26” barrel but primer pockets weren’t good so I settled on 23.0 to be safe and not have to toss my brass after firing.
