$20 says your 150 grain Fusions will blow right through any elk within 300 yards. On the website, Federal claims that the manufacturing process eliminates component seperation. Make sure your friend can shoot, and as long as he doesn't try any severe angles he should be fine. If you're still concerned, Federal loads: 140gr. Accubond, 150gr. Partition, 130gr. TSX, 130gr. Partition, 140gr. Bear Claw, and140gr. High Energy Bear Claw. All of these willhandle any game animal in North America with proper placement. Most people tend to underestimate a well-placed shot with a quality bullet from a small to medium rifle. A friend of mine kills an elk every year with a 50-60 lb. longbow(he shoots several different ones in this weight range), wooden arrows, and Snuffer broadheads. He regularly shoots completely through elk, even when hitting ribs. My point is that if you can make a hole through an elk's heart and/or lungs, it will die. If youknow your friend's nephew can hit a target that size, let him have at it. A bigger gun won't make up for a poor shot.
