I'll be gathering information from members here that shoot the 300PRC regarding brass, powder, etc. Once my rifle is done I certainly want first hand experience from guys I KNOW have it. I love my 300 WM but it's time to move forward and see what the 300PRC offers accuracy and performance wise. It's designed for the new long heavy bullets with the long case neck and a 9 twist barrel should run them well. A buddy is running the 300 NM so we will be shooting side by side comparing performance and precision of both rifles. Pretty excited about it.
