a friend shot a couple small, 250 pound bears with .270cal. 140 CoreLokts, driven about 2,940fps at the muzzle. I loaded the ammo for him, so got the run-down on how well they worked.

The first shot was some 130yards broadside behind the leg - tight, no bone hit - dropped like a stone - dead right there DRT. The second bear, same field the next day was shot by my bro, about 125yards, standing facing him and the shot was in the middle of the forehead between the eyes. It was also "DRT".

The first bear had a hole in his side you could put you size 12 felt pack -80 temp boot inside the cavity just by stepping forward - the ribs and leg meat gone & mush. The entire front end was spoiled - both sides - no meat worth saving.

I would say from the wanting to put 4 quarters each of those young bears in the freezer, the bullet failed on the first, worked perfectly on the second.

Much depends on where you hit them with marginal bullets.
