do you think a 20mm rifle bullet would take town a t-rex?

Having fired a Lahti 20mm rifle, I'd say it would probably kill a T rex with one shot thru the breastbone punching out the heart. If 6" of reinforced concrete and steel won't stop a 20mm, a little flesh and bone won't stand a chance....Show more

probably, given that you are a good shot and know where the vitals are.

If I can take any gun, I take it on with a rpg-7. Low recoil, and you just pick a body part and point. compared to a 2 inch wound channel of the 20mm, a rpg-7 round will blow a melon sized hole all the way thru.
If in doubt, I'll gather all my friends and we'll fire 25 rpgs into it at the same time!

Or I could try a MAW 88mm rocket launcher. its better and more powerful than the rpg-7. get two people to shoot and boom! t-rex down.

I've always wanted to shoot a huge animal with a 50mm punt gun. the recoil is ridiculous, but its like a 4 gauge shotgun. they were used in commercial bird killing, up to 500 birds in one shot....Show more

It is my believe that no shoulder fired weapon has the power to kill a T-Rex.

Granted, if you managed to smash a hip joint with a 20 mm bullet, either HE or AP, he'd probably go down and give you a chance to get a good brain shot and wait for the critter to die.

But you won't be able to carry a 20 mm rifle around like it was a Model 70 Winchester. IIRC, the lightest 20mm Anti-Tank Rifle weight around 100-120 pounds. That is a lot of rifle swing around to hit a fast moving object.

Better that you stick to a jeep mounted 105mm Recoilless Rifle.

No, it would only piss the T-Rex off...I have a 20mm rifle, and I've shot that dang t-rex that keeps wrecking my garden several times, but he just looks up, gives this big toothy grin, and continues to stomp on my tomatoes!!!...Show more

sure,but finding a 20mm or a t-rex is a diffrent story...Show more
