[QUOTE="nksmfamjp, post: 2167177, member: 1951"] I would make 3 key points. 1) what is your neck runout? Your bullet runout will never beat your neck run out. 2) How does your seater fit your bullet? If it wobbles, even a slight bit, it might be worth a custom seater. On YouTube, a guy named Johnnysreloadingbench seems to think this is quite important and shows it in many videos. 3) Are you neck turning? I’m not saying you should, but turned neck should have under 0.001” neck thickness variation. Unturned Winchester could have up to 0.002” neck thickness variation in a single case. Well, I would say TIR under 0.005” is pretty darn good, under 0.010” is good enough, over 0.02” and there is a real problem. Under 0.01” can shoot under 0.75” groups at 100 regularly.....it matters. I measure rolling about 0.01” up from the base, 0.05” back from the shoulder and measure 0.05-0.01” from the tip. [/QUOTE]
