This was incorrect, and caused me to seriously overestimate the accuracy of the Whitworth. It was indeed a outstandingly accurate rifle, but not to the levels I originally stated. In actual fact, the Whitworth was capable of about 3 MOA at 500 yards; not the sub-1 MOA I originally stated.<\/p>\n<p>The numbers recorded at the 1857 test of Enfield vs Whitworth were figure of merit, aka mean radial dispersion. This is the average distance from the center of a group (20-shot group, per British standards) to the point of impact. While much more involved to calculate, this type of measurement provides a more useful measure of accuracy than simple overall group size.<\/p>\n<p>Thanks to John Simpson, David Minshall, and Rob (BritishMuzzleLoaders) for spotting and correcting this mistake!<\/p>\n<p>You can see David&#8217;s article on this issue here: <a href=\"http:\/\/www.researchpress.co.uk\/index.php\/firearms\/british-military-longarms\/small-arms-trials\/measuring-accuracy\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.researchpress.co.uk\/index.php\/firearms\/british-military-longarms\/small-arms-trials\/measuring-accuracy<\/a><\/p>\n<p>Rob has a video on Figure of Merit, which is here: <a href=\"https:\/\/youtu.be\/zAntq2M0o30\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/youtu.be\/zAntq2M0o30<\/a><\/p>\n<p>And John&#8217;s book on sniping can be found here: <a href=\"http:\/\/amzn.to\/2hNHt9d\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/amzn.to\/2hNHt9d<\/a><br \/>\nor on Scribd here:<br \/>\n<a href=\"https:\/\/www.scribd.com\/document\/173949990\/Flyer-The-Sniper-s-Notebook-v4\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.scribd.com\/document\/173949990\/Flyer-The-Sniper-s-Notebook-v4<\/a><\/p>\n<p>Cool Forgotten Weapons merch! <a href=\"http:\/\/shop.bbtv.com\/collections\/forgotten-weapons\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/shop.bbtv.com\/collections\/forgotten-weapons<\/a><\/p>\n<p>If you enjoy Forgotten Weapons, check out its sister channel, InRangeTV! <a href=\"http:\/\/www.youtube.com\/InRangeTVShow\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.youtube.com\/InRangeTVShow<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Support Forgotten Weapons: http:\/\/www.patreon.com\/ForgottenWeapons In my recent video on the Whitworth rifle, I made a rather embarrassing mistake, interpreting &#8220;figure of merit&#8221; accuracy measurements as complete group sizes.
