This was the 2nd time I shot a deer with one. Both dropped in their tracks but the internal damage on both is way too much. Shooting 30.06 150 grain. Bullet mushrooms great. Hit them in the top of the shoulder but pieces of the round break off and hit the guts ruining the lower edibles. Round stays in the animal.
Those rounds are like a grenades and...that's it for them.

Im amazed you found the bullet in the animal.

This

I am too. The guts were hanging out what appeared to be an exit hole

What was the shot angle?

Maybe 10 degrees. That round is pushing 3000 ft/sec and it was a 200 yrd shot. I didn't think about this but maybe... just maybe it was shot by someone else at one time and the bullet lodged in the animal...because I saw a definite round splash on my bullet. This round weighed about 144 grains. I don't think my round would have weighed that after hitting the shoulder blade and blowing up the guts.

Where in the animal did you find the bullet? Have seen more than once where heavy bone was hit fragments of it became projectiles inside the body with some real damage done. It could have been bone that busted the gut.

Exit side with the nose toward the entrance side...weird. That's what I'm thinking... I'm finished with the barnes though. The deer I got last year using the same round in the same place exploded...something took out the guts and what was left of the bullet exited through the nose.

I am amazed that you found the slug? I have shot/guided numerous deer that were shot with Barnes 150 grain bullets and have never had one stay in the animal. More often than not, the Barnes slugs made .308 holes going in and .308 holes going out. All of the deer have been found dead, but without any blood trail. I do not like them for Texas whitetail.

More and more people every day are seeing the light that these bullets aint all they are cracked up to be. I remember when I posted my horrible experiences with them here on the forum you would have thought I slapped someones momma or something. Now days I see more and more opposition to them on the various forums.

I have never been a fan of them myself... on the other hand I have used them myself and read multiple stories of others and explosive expansion is never one of the complaints. Usually its a lack of expansion and lack of blood trail.

Get a good scale and weight that bullet, chances are it weights over 95% of what it did before it was shot and whatever punctured the guts or went out the nose was not that bullet.
