As others have stated, save these bullets for African game. I shot a cow elk in 2003 with a 120 gr. A-Frame out of a .25-06 Ackley. Although the elk went down in four or five seconds, it looked like the bullet could have gone through three elk standing side to side. A friend of mine used this same load on mule deer in 2003 and got end-for-end penetration.
