I don't neck turn unless needed if the brass necks are not having enough clearance in the chamber. Neck turning .005-to under .001" to clean up necks is good too if you want to eliminate all the variables to get good accuracy and you may need to use a bushing die if you turn the necks. You will get less neck tension if you used a non bushing die. Most shooters dont really need to turn top end quality brass like Lapua or Petersons, but the other day I noticed variation in my 300 Magnum Lapua brass by as much as .002" , from .014" to .016" . I had to neck turn to .0135" anyway to give enough clearance of .005" in my neck chamber. Match shooters with custom tight neck chambers do neck turn. As for hunting, neck turning is not really necessary. Depends on personal preference on how you view accuracy as your goal.Do you turn the necks as a step in brass prep? As we square primer pockets, debur flash, chamfer ,etc . for brass prep. or only when you have accuracy problems?
I don’t think it works like that. Accuracy is sort of like cooking…if you start with ingredients that you don’t like, they aren’t going to taste good even if they’re perfectly cooked! I’m in for experienced answers to your question though….So do any of you have an experience where changing seating depth, powder, charge weight, bullet type failed to give the accuracy you sought, and neck Turing did?
If your looking for max accuracy and consistency its a no brainer.
How much do you remove to clean up? I cleaned up about .0005" off the Norma 300 , just some high spots. I may start cleaning up new brass once I buy them in the future. They do have some small variations.This
I like to do a clean up on my necks on non Wby brass. This allows for a consistent neck tension.
That is kind of the point of the thread Tackdriver had on his 300wm. The clearance on his brass caused accuracy issues that thinner necks fixed. That is far from the norm but it can be a problem.So do any of you have an experience where changing seating depth, powder, charge weight, bullet type failed to give the accuracy you sought, and neck Turing did?
That was with his known/good load though. You don’t just pick some random load out of a manual, neck turn the brass and then your shooting bug holes?That is kind of the point of the thread Tackdriver had on his 300wm.

Just until there is some fresh brass showing 360 around the neck.How much do you remove to clean up? I cleaned up about .0005" off the Norma 300 , just some high spots. I may start cleaning up new brass once I buy them in the future. They do have some small variations.
Forester hand turner and case chucked up in a drill for me also.I use a Forrester neck turner that is basically a converted case trimmer. I use a drill to drive it so I can do 100 cases in no time.
It was a known load in Norma brass not Lapua brass and he figured out his loaded rounds were too tight in the chamber. If you read the whole ordeal he couldnt find any load that shot under 1.5". The original question was had anyone seen a accuracy improvement by turning necks, there you go. I've experienced the same thing when trying to run too little neck clearance. Generally speaking most people wont see a difference by turning necks. Most of the high end brass is pretty consistent now days. You can see it when you skim necks. Brass like Winchester and Remington is usually off a couple thou from one side to the other. When everything is sized from the outside that puts the bullet off center.That was with his known/good load though.

Do you remeasure the loaded bullet diameter again and get a new bushing .002" under bullet diameter? What is your preference? Since you removed some material, possibly about .001" each side.Just until there is some fresh brass showing 360 around the neck.

How do you measure tension?You didnt ask me but I typically try to run .003 tension in hunting magnums. Any less and you could see bullet movement in rounds that sit in the mag box.
Exactly…he had a known, good load with acceptable accuracy for himself. Changed brass and ran into the neck clearance issues evidently. He was not starting from scratch and couldn’t find any load that shot, turned his necks and then bam, magic accuracy. I agree that most people won’t see a difference in accuracy by turning necks. It could help and I doubt that cleaning up the necks would hurt anything.It was a known load in Norma brass not Lapua brass and he figured out his loaded rounds were too tight in the chamber.
