I installed a D-Fender o-ring on my extractor and took it out for a test drive today. I shot 20 rounds of 5.56 Federal XM193 55 gr (brass cased), and 20 rounds of Herter's .223 55 gr (polymer-coated steel cased). All fired and ejected without a hitch. When I was done, I noticed that all of the brass casings from the XM193 were clustered together at about the 2 o'clock position, approximately 12 feet away. All of the steel casings from the Herter's were clustered together at about the 4 o'clock position about 15 feet away. This is no big deal but I am just curious as to why the brass and steel casings ejected at different angles. Could it be the power difference between 5.56 and .223? Or perhaps the brass bounces off of the deflector bump better than the steel?
Anyone know the answer? Or have a good guess? |

Well, that makes sense. Thanks for the response guys. As I mentioned in my post, I wasn't worried about the ejection patterns, I was just curious. Thanks for the diagram gotigers. My pleasure. Not my pic, but I have find it useful for explaining ejection angle. |
