When we talk about rifle shooting, the words accuracy or precision come up a lot, as that is the aim of everything to do with rifle shooting (no pun intended). But, when is it correct to use accuracy vs precision, in what context and what is the difference between them? Especially concerning measurement when shooting, just because something is accurate, does not mean it is precise. Let us take a look at how they differ and when to use which one. In Short You can measure your shooting results in both accuracy and precision. Precision measures how close shots are to one another, so you can measu ..read more

The 6XC II

The 6XC II Chamber works perfectly with the Norma 6XC brass and resolves the “sticky bolt lift” issue. The original 6XC chambering was designed based off the usage of 22-250 brass which typically has a web diameter in the range of .461″-.463″.  The area of the chamber just forward of the web on the original 6XC chambering was .4695″ which left plenty of clearance.  When Norma 6XC brass became available Norma appears to have developed the base of the case from the .308 Winchester line of cases which have a larger web diameter.  The web diameter of the Norma brass typically measu ..read more

6mm BRX

The 6mm BRX vs  6mm BR The 6mm BRX uses 6mm BR brass as the base brass.  Making the 6mm BRX is easy and involves loading up 6mm BR brass and fire forming it in a 6mm BRX chamber (the fire forming loads can also be very accurate).  The net result is the 6mm BRX case that has a 30 degree shoulder (same as the 6mm BR) but the body of the case is .100″ longer than the 6mm BR and it picks up a fair amount of additional powder capacity over the 6mm BR.  The 6mm BRX has the capability to easily push the 105-108 gr. 6mm bullets up in the 3000 fps range. 6mm BRX vs the 6mm BR 6mm ..read more
