    Hornady Match dies 6.5 prc

    I’m having trouble with my set of Hornady match dies. The only way to get -.002 on a fire case is to have the die so far down that it’s chipping the teeth on the Hornady lock and load bushing. I’m running a .290 neck bushing with .002 neck tension with once fired Hornady brass. Any ideas? Thanks

    Nonsensical Headspace Measurements on 223rem cases...??

    How would full-length sizing a case increase the headspace measurement on a .223 case, and charging/seating/crimping decrease the headspace measurement?? This weekend, I started taking headspace measurements on some 223 cases in my stockpile in various states on the way to being reloaded, in...

    I was speaking with Krieger barrels and they said that if the bolt is chromed, there MAY be insufficient headspace with the barrel. The reasoning being that if the bolt is made to milspec, and then chromed, the chrome will eat some headspace. I have a Young Mfg National Match Chrome Bolt...

    Gunsmithing Too much headspace?

    So I found a bolt for my project rifle and borrowed some headspace gauges and they worked properly. Bolt closed on the go gauge and did not on the no-go. So everything was kosher and I shot the rifle with a shoestring. It seemed to work fine. I checked it today while reloading at another...
