    Chamber Question/Education

    I was hoping for a little education about chambers and bullet sizes, specific to these new “heavy for caliber” bullets. How does chamber cut influence performance with various sized bullets? Or is it not even a thing? Specifically, I have a match chamber for a .300 PRC set for 225gr...

    Chamber Preasure

    What happens to chamber preasure if you work up a load at 1600 ft, and then go up to 6500ft. I understand that preasure will be higher if the temps are higher, but unclear about the change with altitude. Thanks
