One of the first things I did to insure reliability of the ammo I handload was to buy a Dillon case gauge. My brass has been shot thru many different chambers but after it is resized now and it gauges I know it will chamber and lock up . If a case fails to gauge the first time I will try to resize it again if it then gauges fine , if it don't it goes in the recycle bucket I won't even save it for the bolt guns. Consistancy when loading for AR's counts alot to insure reliability. MB
