That load was 75 grains of adi 2213 s/c from memory they were doing around 3200fps the projectile was 168 Amax, nos custom brass, fed primers.
I think Reloader 22 gave similar results.
The amax was brilliant at all ranges on these small bodied goats, other projectiles would just pencil thru and not release any energy.
The amax also seemed to hit harder the further I shot it.
