That was just a baby bull moose - 6 months old, but the front leg bone the bullet went through, was over 2" in diameter. It removed 2 1/2" of length from the bone, then parts of it kept going into the boiler room. It was just 'enough' bullet, but I doubt it would have gone through an adult moose's leg bone. The impact velocity was only about 1,800fps. Rod thought it worked just fine, but I always felt it was too thinnly jacketed - and it is thin. I think the 225gr. Hornady .375 sized down would be much better - a little flatter shooting and with it's 1/16" (.063") thick jacket, has proven to penetrate much better on all manner of materials & deer during Rod H.'s testing.
That shot, taken through the leg was the only one presented due to the angle and 200yard range or I wouldn't have shot him there. It worked - this time.
In retrospect, I would have preferred a bullet of tougher construction.
