I remember years ago running TZZ/IMI 55 ball over the chrono in 20 inch tubes and seeing 3300 and just over more or less as my memory goes.. they did seem like awful hot rounds, they were 5.56 and fired in a 223 chamber.. oh the horrors...

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
