I shot a cow elk in Colorado during the early 90's.
Used a 140gr X out of my 270. Was a struggle getting them to shoot. Finally found a load and went hunting.
Elk was moving through the trees at about 60 yards. Took a shot and there was no reaction from the elk. Herd continued downslope and when following the tracks in the fresh snow found zero blood until the elk was spotted all piled up. Right through the ribs.
Was a little unnerving, but all is well that ends well. I attributed it to elk being elk, but years later wondered if I did not get expected expansion. No was of knowing now, as I do not remember the butchering process as it was getting late in the day and we a very long way back to camp.
Finished the remaining shells and swore off X bullets. Tried XLC's and swore them off. Then one of the Superior ammunition guys talked me into trying TSX's at the range one day. Have not looked back.
