He’s angry because you’re pointing a .50 BMG rifle at him. Duh.
Ah. Then I’d put the gun down and say “Just kidding.”
I actually have a foolproof plan if he’s angry about something else. They say that anger turned inwards is depression. I’d turn his own anger back on him. Maybe mess with his self-esteem. Remind him that all of his friends went extinct 65 million years ago. Get him really nice and super-depressed. Then hand him the gun.
Problem solved.
Even worse, there’s no lady T-Rex and his arms are too short.
IIRC James Brady was press secretary or somesuch, a staffer not a politician. So the joke falls like a lead round.
Good point! Poor guy…
He was getting an easy meal regardless. I just spared myself the unpleasantness of being chewed.
A guy on “I Survived…” (why DO I watch that show? It completely stresses me out!) was attacked by a 500 pound grizzly. He managed to shoot it twice with a measly .33, but those nearly direct hits didn’t even faze the bear.
So I’m thinking that unless you can fell him with one shot (to the spinal cord? the kidney?), you’d better pray for a quick death-by-dino.
I’d prefer a 40mm Bloop gun.
Generally, animals don’t fight to the death unless they absolutely have to. Even a non-lethal wound to the chest would probably cause the T-rex to back off and reevaluate his strategy.
Thus, a shot to the dcenter of mass, where I have the greatest chance of hitting.
This one.
You don’t even need to sever the spinal chord; the concussive shock to the chord would take him out.
Imagine the taxidermy costs!
So much to respond to…
First, some previous threads-
What weapon should I use to hunt a Tyranosaur?
anatomy of Tyrannosaurus skull/brain
. Now I wonder: in the movie Tremors, one of the characters has a very big gun and he loads it with some truly huge cartridges. But the 600 Nitro Express round in fact isn’t that big. Here’s a picture of one with a .50 BMG and a .45 ACP for comparison. So what gun does take those banana-sized cartridges?
A .50 BMG rifle may be easier to get than a classic elephant gun, but might not be the best for shooting big game. WIkipedia’s article on elephant guns says

He isn’t angry. He’s hungry. 
I’m imagining the baddest full-length leather coat with matching boots and gauntlets EVAH!
This, and with all the gun-heads here I’m a little surprised it took 32 posts to figure this out. A high-energy bullet hitting a fluid-filled skull is gonna squish everything inside from hydrostatic shock, isn’t it? I don’t see any reason it would be necessary to score a direct hit on the brain. I’ll listen if someone has a sound explanation why this wouldn’t work, but until then I choose sweet and sour rex.
ETA: OK, so I see a couple posts that suggest I might be wrong. I’ll stick by position, though, since I’m likely never to have to shoot a T-rex anyway.
Oh! To answer my own question, I found the invaluable IMFDB site, which says that in the first Tremors movie the character Burt Gummer was firing an 8-gauge shotgun. Pictures here
Hey! Check out post 30!
My apologies.
Dang, where’s the “half the skull missing” smilie?
Regarding a torso shot against a T-Rex, I couldn’t find a cite but I thought I once read somewhere that in T-Rex the costal cartilage connecting the ribs to the sternum was heavily ossified, meaning that it had a lot of bony armor protecting it’s chest. True or not?
I’ve never fired a gun. I’d miss him by a mile
How did they let you into Ranger school?
He hypnotized the instructors?
Use the bullet to fire off a warning shot. (Hey, he doesn’t know how many bullets you have left, right?) After that you could just keep him at bay with the gun trained on him until help arrives.
