O.K. lets hear it for really big game hunting. The weapon must be able to be shoulder fired and not a rocket.

I would use a Barrett 82A1 in 50 BMG, probably AP type of round.

Actually, if you are strong enough to hold up a Barrett offhand, you're strong enough to shoot it....  I'm not!!!

I've fired a Barrett semi-auto off a bench and found that I have 12ga shotguns that kicked me harder.

Great fun to pick out a target at a thousand yards and watch the rocks fly...:wink:

I've seen that video of towel heads shooting the T-Rex.. They sure do babble when they're picking themselves up off the floor..:lol:

.700 Nitro Express ?

For a true shoulder fired rifle, that's probably the largest caliber i can think of.  Makes the .577 look kinds small, but you can load the t-rex to much higher pressures so it can sure churn up the energy.  .585 Nyati     ...    same performance as the t-rex but thought i heard it was worked around a heavily modified 600NE case.?.?.?.?.?

lots of crazy stuff on that bmg case.  just a lot of powder to burn (and handle) for me to consider it a viable shoudler fired weapon.  Although it surely can be done if ya choose to.

later all.  klallen

Somewhere there is a video of a guy shooting a 4 bore single shot rifle. I think the projectile for the 4 bore weighs 2000 grains.

Its big. I would not willingly shoot that either.

I have fired a Barrett bolt action from a standing position, it is not as bad as some 12 Gauges that I own.  I shoot a .600 NE a couple of times a year, and that will knock your teeth loose, but that big lead slug may not penetrate deep enough.

The size and weight of an adult T Rex is: measuring up to 13 metres (43 ft) in length,up to 4 metres (13 ft) tall at the hips,and up to 6.8 metric tons (7.5 short tons) in weight.

Where as an African Elephant is spec'd out at:

African elephants are bigger than Asian Elephants. Males stand 3.64 meters (12 ft) tall at the shoulder and weigh 5455 kg (12,000 lbs), while females stand 3 meters (10 ft) and weigh 3636 kg to 4545 kg (8,000 to 11,000 lbs).

So the Elephant is as tall as the T Rex's hip.

For the 50 BMG round, if I was to load my own, I would use the 800 gr Bar Solid Bullet at 2800 fps or maybe 570 grain A Squared at 3,100 fps, I figure about 14,000 pounds of energy either one. Plus remember with the AS-50 in the Military they have an effective kill range for cinder blocks of 2 1/2 miles. My 600 NE has about 8,000 pounds of energy.

I don't have specs of the .577 NE or the .577 T Rex. I do know that the .700 NE is a really powerful cartridge probably in the 10,000 pounds of energy range, but I can't find specs on the cartridge, but they have 1,000 jacketed grain bullets for the .700, 900 grain jacketed for the 600 NE and 585 grain for the 577 NE.

So lets get creative, this critter will not only stomp you, it will eat you.

So lets get planning for this hunt,

Jerry

I watched the video, these guys didn't have any meaningful training on how to shoulder fire a heavy recoil rifle, but it was funny, except no one dislocated their shoulders, but a few were knocked on their a$$.

ok, been thinking about this for about 12 minutes and here's what i've come up with.  t-rex hunt booked for this fall.  some thoughts and considerations.

it's gonna have to be a brain shot obviously.  instant incapacitation.  once within range to make a killing shot, we certainly can't have a wounded t-rex scurrying about the place.  i really don't think any modern bullet's gonna break an animal this solid down.  so brain shots it is.  i'm thinking it'll have to be a shot on animal while his head is down eating.  maybe we hunt over bait or simply look for fresh kill.  don't really think we want to be shooting up through jaw bone (in efforts to get to brain) at the height this guy will be standing so quickest way to the brain with least obstruction may be head down throught the top, just above between eyes or where the ear would be (they even have ears?).  i guess first and formost, we better have a good understanding of where the brain is located.  heard dino brain aren't really that large so that certainly could cause a problem.

i'll take either a .585 Nyati or a .577 Tyrannosaur in an 18lb. bolt rifle loaded with an A-Square 750 gr. Monolithic Solid right around 2500 fps (10,200+ #energy).  attempts to put one right throught the old thinking cap.  not entirely sure why i need it to be a bolt action.  after triggers pulled, if he doesn't fall, is a back-up shot even necessary  :confused:  .  i suppose in this case, your ph had better have quality back-up.  i'm thinking something designed to deliver a large explosive type warhead.  :sad:  something's gonna have to stop him.  if the first 750 only pissed him off, a second through the gutt or hip as he bears down on you is gonna do nothing to brighten his disposition.  running's not an option.  you're not sitting in a vehicle for quick get-away cause you sure as hell didn't drive within shooting range of this guy without him noticing.  all you can do is stand and fight so the ph needs something that'll make body parts fly.  just make sure he hits him below head.  you'll be bleaching that bugger out for the european mount  :shocked:  .

later.  klallen

Well, I`m gonna be totin a true T Rex hunter:wink:

The South African  Denel-Mechem NTW-20mm Anti-Material Rifle qualifies quite admirably for the title of Worlds Most Powerful Sniper Rifle, and I don't think that this will be disputed. This rifle fires 20mm cannon rounds as favored by helicopter gunships, fighter aircraft, warships and armored vehicles.  Since the 1930's up until recently the 20mm round has never been deemed suitable rifle ammunition by the military, as the rifle required to fire it would be fantastically heavy and way too cumbersome for any infantry soldier to carry.  Plus the fact that the 20mm cartridge produces such excessive recoil that no-one would withstand the force.
But this didn't stop the Japanese in 1937 from building about 40 rifles in 20mm caliber.  The semi-automatic Kawamura Type 97 20mm anti tank rifle was a very heavy gun at 110 lbs and at nearly 7 foot long it needed a team of 4 men to operate it, a gunner, a loader, and 2 ammunition carriers. The rifle could be taken down into 2 parts but generally it was carried by 2 men with a handle fitted at each end of the gun.  The violent recoil could also injure the firer as it was not adequately suppressed and brave volunteers were needed, but there were always some hardy souls willing to fire it.
 With Armor penetration at 3cm from 350 meters distance and 2cm from 700 meters, the Japanese thought it a worthwhile tank killer.



Below is a picture to illustrate the size of a modern 20mm round, standing next to the more common big caliber rifle rounds.  20mm cannon rounds usually have the bullets painted bright blue, with a description of the dimensions and type of cartridge painted on it in white letters.

I would suggest an RPG7 as the backup gun for the T Rex hunt. Light, portable and accurate enough on large targets.

Makes sense 72. I know a bunch of fellas that have lost legs,arms,eyesight and their lives inside the protection of a Bradley Fighting Vehicle after an RPG tore through it.
Very nasty weapon for certain.

What bothers me about it is we don't have anything to match it for our militaries use.

My choice for  T-Rex hunting, would be a 50-20, that's a 20mm cannon casing necked to 50 cal, loaded with a 750gr A-max, the back up round would be a Raufoss round, that's a slug that has a penetrator in it, the penetrator is preceded by a jet of hot gasses generated by a small shaped charge of RDX!

I'd try and find a T-rex kill, or other dead animal, set up on the side of a hill or other suitable high place and be approx. 200 to 250yds from the kill!

72,

Ma Duce is available to the public, but that super ammo they use isn't. I think the RPG idea is flawed, becuase it would probably detonate on the surface of the critter, maybe cause a fatal wound, but the hunter may not survive the experience before the Rex dies. If you look at the cage they put on a Stryker, to stop RPG you see the flaw in the RPG concept, when I was in Vietnam, I saw a tank with chicken wire set up around it to stop RPGs, the shell would just hang there in the wire. But I think the RPGs aren't that powerful to take down a T Rex. But there are other Shoulder Fired or Man Portable Missiles, but that would take the fun out of tracking a T Rex and shooting him with a good old fashion rifle.

I still think a Barrett would be the preferred weapon, if you had the training to shoulder it properly. I would want some of the modern 50 cal ammo the Army uses, the stuff that blows thru one layer, then has am explosive charge, but you can't buy it, or lets say legally.

Jerry I have had RPGs fired in by direction (we called them B40s) and I think it would have plenty of killing power for any animal.

I have what you might call intimate experience with them. One of them landed about 3 feet from my head. The guy was shooting at a tank that was about 15 feet away and I was only 12 feet away.

You know if you shoot an RPG at a tank at night you really had better hit it. If you don't  the consequences are dire.

I'm suspicious that a brain shot on ol' T. Rex would not do much even if you knew exactly where to place the shot.  Most of the brain activity in reptiles is in the spinal column, IIRC.  Better, thinks me, to break a hip or knee so it can't readily chase you while it bleeds out.  (Besides, who would want to spoil that trophy skull?)
