A Gun For Dinosaur Vs. T-Rex

Saturday, July 5th, 2025

If you’re well-read in science fiction, there’s a good chance you’ve read L. Sprague de Camp’s “A Gun for Dinosaur.” Now Scott from Kentucky Ballistics tests just how big a gun you need to take out a ballistic gel replica of a T-Rex skull.

Guns used:

  • .45 ACP (dual barrel)
  • 10 mm
  • .44 Magnum
  • .50 Magnum
  • 12 gauge shotgun
  • .45-70
  • .223
  • .460 Rigby
  • .577 Tyrannosaur (naturally)
  • .700 BMG
  • 4 bore (1″)
  • .950 JDJ

    • There are evidently only 20 .577 Tyrannosaur rifles, and only four .950 JDJs, in the world. One of the latter sold for just under $1 million last year, so if resurrected cloned dinosaurs do make a comeback, hunting them will probably be a very expensive hobby…

    Firing Ridiculously Large Caliber Guns

    Sunday, August 4th, 2013

    So Ace of Spades linked to this video of someone firing the .950 JDJ, the largest caliber center fire rifle ever made:

    As someone with an irrational* desire to own something chambered in .50 BMG, it got me thinking: what other videos of people firing ridiculously large caliber guns are there out on the Internet?

    I found some. (NSFW language in many of these.)

    How about .577 Tyrannosaur?

    .585 Nyati:

    .600 Nitro Express pistol:

    .600 Overkill:

    20mm rifle:

    And here’s the top loading version of the 20mm, in case you’re being attacked by multiple tanks at once:

    And here’s the recoilless version of the 20mm rifle:

    I think the technical word for that is “bazooka.”

    And here’s the recreation of a one-mile kill shot with a Barrett M82A3 .50 BMG:

    *Irrational in that the use case for such a gun starts to get into things like “Well, I’ve already killed several of the drug lord henchmen attacking my house, now I need to put a round through their engine block to keep the rest from escaping!”
