Warning &#8211; classic Heinlein attitude displayed throughout.<\/p>\n<p style=\"text-align: left;\">In A Gun for Dinosaurs, Reginald Rivers talks about using a .600 Nitro Express in the Cretaceous. A .600 NE is a <em>huge<\/em> gun, but whenever I think of dinosaur guns, one always springs to mind: the Holland &amp; Holland Saurian 4 bore.<\/p>\n<div style=\"padding-bottom: 2px; line-height: 0px;\"><a href=\"http:\/\/pinterest.com\/pin\/287737863664217906\/\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"http:\/\/media-cache-ec5.pinterest.com\/upload\/287737863664217906_E45qnSW0_c.jpg\" width=\"554\" height=\"346\" border=\"0\" \/><\/a><\/div>\n<div style=\"float: left; padding-top: 0px; padding-bottom: 0px;\">\n<p style=\"font-size: 10px; color: #76838b;\">Source: <a style=\"text-decoration: underline; font-size: 10px; color: #76838b;\" href=\"http:\/\/www.hollandandholland.com\/excellence.php\">hollandandholland.com<\/a> via <a style=\"text-decoration: underline; font-size: 10px; color: #76838b;\" href=\"http:\/\/pinterest.com\/drhypercube\/\" target=\"_blank\">John<\/a> on <a style=\"text-decoration: underline; color: #76838b;\" href=\"http:\/\/pinterest.com\" target=\"_blank\">Pinterest<\/a><\/p>\n<\/div>\n<p style=\"text-align: center;\">*<\/p>\n<p style=\"text-align: left;\">A little bit of history&#8230; Before there was modern <a href=\"http:\/\/en.wikipedia.org\/wiki\/Smokeless_powder\">smokeless powder<\/a>, there was black powder. Both propellants get called gunpowder, but they are <em>not<\/em> the same thing. Black powder burns much more slowly than smokeless, and thus, with reasonable barrel lengths, just can&#8217;t produce muzzle velocities (how fast the bullet is going when it leaves the barrel) that hunters take for granted today. There are 2 terms in the equation for kinetic energy &#8211; velocity and mass. Since our black powder velocity is constrained, upping the mass is the option that&#8217;s left. The bore number is how may lead spheres of bore diameter it would take to get to 1 lb. A round ball bullet for a 4 bore weighs a quarter pound! Wikipedia&#8217;s <a href=\"http:\/\/en.wikipedia.org\/wiki\/4_bore\">entry on the 4 bore<\/a> is quite good, if you&#8217;re curious.<\/p>\n<p style=\"text-align: left;\">I&#8217;m assuming the Saurian is built for black powder (or black powder equivalent) loads, though it&#8217;s somewhat academic. This is an art gun &#8211; an opportunity for engravers, smiths, stockmakers and cabinet makers to show their skills. I have an old magazine somewhere with more pictures of the Saurian &#8211; if I ever find it I will scan and post. The case, as I recall, included a glassed in area with a display of varous dinosaur fossils. Is the Saurian what I&#8217;d choose for my time travel dino hunt? Hell no. But it&#8217;s not like I&#8217;m going to have to choose anything any time soon.<\/p>\n<p style=\"text-align: left;\">And to finish, via <a href=\"https:\/\/twitter.com\/TetZoo\/status\/283548695868346368\">@tetzoo<\/a>, a major dino hunting disappointment.<\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/english.bouletcorp.com\/2012\/12\/20\/when-chicken-ruled-the-earth\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-19318\" alt=\"Dinosplumes01\" src=\"http:\/\/hawkdog.net\/wordpress\/wp-content\/uploads\/2012\/12\/Dinosplumes01-734x1024.jpg\" width=\"491\" height=\"684\" srcset=\"http:\/\/hawkdog.net\/wordpress\/wp-content\/uploads\/2012\/12\/Dinosplumes01-734x1024.jpg 734w, http:\/\/hawkdog.net\/wordpress\/wp-content\/uploads\/2012\/12\/Dinosplumes01-215x300.jpg 215w, http:\/\/hawkdog.net\/wordpress\/wp-content\/uploads\/2012\/12\/Dinosplumes01.jpg 765w\" sizes=\"auto, (max-width: 491px) 100vw, 491px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ripped from the Twitter headlines!
