I've shot about 900 rounds through my 7mm WSM
. The reloads that I shoot chamber well, and give satisfactory (.5 and less @ 100 yds) results. I've always just resized the neck and as stated never had chambering problems. I measure each shell after they are loaded and the neck dimension is pretty consistent at .315
Would neck turning improve on what I am shooting already. I read that even a slight turning inside and out would improve the center line relating to case, bullet and bore alignment.
What are your thoughts?
