Well Obviously - Just look at the difference - Doh!

I had a 275gr. from my .375 BRNO stop inside a prairie picket pin - Richardson's Ground Squirrel by make, no more than 1 1/8" in diameter - the bullet stopped under the hide of his back. Slit the skin with a pocket knife and it fell out into my hand. Even the .303 would shoot through them - sheeeeeesh!
