Why are the pressures and forces so much less with the 223 and Grendel ?
Is it just because they're rated for semis ?
To answer this question, it's all about case capacity. The 260's case holds more powder than the Grendel case so it is going to be SAMMI pressure rated much higher. It has little to do in what type gun it's to be operated through.
