So nothing fires off a thread more than a debate about penetration variance between .22 and .177. My anecdotal evidence: .177 penetrates further than .22. It's why I dont like using .177 on birds and squirrels because the pellet flys straight through. The theory: ballistic coefficient determined retained energy so a .22 should pen further than a .177. In the red corner: BSA Ultra SE in .22 (11.4 ftlbs) firing AA Diablo Fields 15.9Gn. In the blue corner: BSA Scorpion SE in .177 (11.6 ftlbs) firing JSB Heavies 10.3Gn. According to Chairgun these pellets have the same ballistic coefficient - but they dont behave the same. Exibit A: I bought some modelling clay. It was cold and hard. You can see that the .177 pens deeper than the .22 /..... Then I warmed up the clay and tested the .22: Boy did the .22 pen! The cavity was huge. Then the .177. It didn't go as far!

I'm writing some software which does a few aerodynamic calculations. As I was working some figures out I got to wondering what the BC of shotgun shot is. Obviously it's going to be absolutely dire, but just how dire? All I find find online are BC tables for rifle bullets and airgun pellets and nothing for shotgun shot. Anyone know of any site where this kind of information has been determined and published?
