Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
BotR and Ian drinking whisky and hanging out? Sweet.
Monty Python! Holy Grail was one of my favorites growing up. I used to be able to quote the whole damned thing from memory. That's been displaced by far more useful things in the intervening years.
The 50% radius is called the CEP, or circular error probable. It is still used quite extensively to rate the accuracy of air-dropped weapons. You can convert to a single sigma distance, and can derive a three sigma distance from that. Three sigma distance should be 99.7%, damn near every shot. Group sizes for a CEP of 10cm are as follows:
CEP (50%) - 10cm radius, 20cm diameter (3.94in radius, 7.87in diameter), 0.33MRAD (2.29MOA)
DRMS (63% to 68%) - 12cm radius, 24cm diameter (4.72in radius, 9.45in diameter), 0.4MRAD (2.75MOA)
R95 (95%) - 21cm radius, 42cm diameter (8.27in radius, 16.5in diameter) 0.7MRAD (4.82MOA)
2DRMS (95% to 98%) - 24cm radius, 48cm diameter (9.45in radius, 18.9in diameter) 0.8MRAD (5.50MOA)
3CEP (99.7%) - 30cm radius, 60cm diameter (11.8in radius, 23.6in diameter) 1.0MRAD (6.88MOA)
This is pretty reasonable to be able to hit a soldier in the chest if shooting center chest at 300M. Given the statistics, this is more than good enough for the second world war. Given that most tend to measure groupings from center to center of the most spread rounds, I think this would correspond to 3CEP, so it could be a useful point of comparison.
Random thought from a distance drive one day, related to production of rifles during wartime:
One of the greatest benefits for the US military is the civilian shooting community. Consider, the US Army could requisition another half million M4 or M16 type rifles per year without exceeding installed capacity for the civilian market. Same thing goes for ammunition.
Wonderful. I'd been meaning to up my manliness factor.
