Now, the American cartridges run just fine; I have a body of experience in this myself, including with steel cased 5.56 which runs just fine as you mention.<br /><br />I can agree that maybe the body of the article is a bit provocative, maybe it sounds even a little like military reformer talk (which I certainly hope to distance myself from these days), and I'd probably write it differently if I wrote it today instead of two years ago (it was originally posted to another website before I started my blog here). Having said that, I think the trend is interesting, and provides a clue to American and Russian cartridge design that isn't talked about.Nathaniel Fitchhttps://www.blogger.com/profile/15011387972300996469noreply@blogger.comtag:blogger.com,1999:blog-5557913977913148366.post-71138981495426748592014-02-07T17:17:44.662-08:002014-02-07T17:17:44.662-08:00Ask yourself what the purpose of case taper is, th...Ask yourself what the purpose of case taper is, then ask yourself if more is better.<br /><br />As long as reliability is acceptable, case taper is a none issue. When you put a male cone (cartridge) inside a female cone (rifle chamber), it doesn't matter the angle of taper, as soon as there is rearward movement out of the chamber you have a 100% break in cartridge to chamber contact. More taper is better when the cartridge lacks "springback" such as being made of steel, but enough folks have run steel cased 5.56x45 through ARs to show that extraction isn't going to be a huge issue.<br /><br />SordidPandahttps://www.blogger.com/profile/00657526230826604643noreply@blogger.com
