FWIW, for the most part ammo that has FMJ in it, isn't great and can be way worse than not great. Maybe save for Lapua FMJ possibly. Some 62s, and especially some weight sorted 62s, but who has time for all that.
Find ammo, for your twist, lets say 73 or so and down, it MIGHT shoot 75/77 but you won't know till you try.
So look for 73, or 68/69, or 52 bthp bullets. Or something like 50 or 60 vmax. Anything but FMJ will tell you if your barrel is better than what you've typed.
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
