I got a chance to read the second part and it was an interesting article. Thanks again for posting Feenix. As I read the thread, I see we hit on heavy for caliber, velocity, spin rate, horsepower, torque and dead is dead, and physics.
I hit a deer with a very low horsepower Toyota with a four cylinder traveling at 60 MPH, and it was dead. Two years later I hit a deer with my extended cab Chevy K2500 doing 15 MPH and it was DRT with a broken neck. The Chevy had triple the horsepower of the Toyota and a lot more torque. That would make me think that larger caliber or heavy for caliber is best. Or it put me in the dead is dead group.
I am just a stupid mechanic, but I enjoyed reading the article in the original post.
Happy hunting to all of you, and have a great day.
