[QUOTE="elktaker, post: 1104176, member: 86786"] I am having issues with neck tension. I have a 7mm wsm pacnor barrel. I went to range yesterday to check what my drop was a at for 300 yd. I happen to have 5 once fired cases that I saved for 300 group. Others had been fire 3 to 5 times a neck thickness was noticeably thicker and bullet seat with different pressure on press. I wanted to establish that my 100 yard zero was right so I fire 3 of older brass after one cold bore shot. Group was just over an inch. Load development showed 1/2 groups. Another group yielded the same 1 in. Groups were very vertical I moved to 314 to check my with newer brass group measure .71 moa (5shots) which I am happy with. All group were shot off atlas bipod prone. Does this correlate with a neck tension issues, correct? What do I need to properly adjust the tension uniformly? I am Planning on get a neck turner. I need to be able to bump shoulders back also if that makes a difference (.001 in) full length sizing with a redding die currently. [/QUOTE]
