I have shot a few animals with the older 85xbt Barnes, at 2900fps and it really needed some resistance. I killed Axis deer and even an heavy Oryx, but zipped right through 2 jackrabbits! The 100gr Corlokt was the ultimate in the 6mm Remington on Est Tx deer. I myself much prefer the faster 6mms over the 243 or similar wildcats. I just think they kill better, but "its sixes", as they say. I know one fellow who swears by the 95 Partition in his 240w and another who uses nothing but the 100gr Hornady Boat Tail, even on elk! The last animal I killed with any 6mm was 2001, a 90gr NBT from a 6mm/284 on a 150yd antelope doe. Fist sized exit, but it was antelope. Good luck to you Pard.
