Should I neck turn?

The only way you will know is to test it for yourself.

Yup... that’s my plan too!

Honestly, it doesn't matter much. I do it for two reasons.

One is that it allows you to size with light neck tension without running into issues where one case is .001" thicker than the next. This is the primary reason I do it.

The second is that you will find a couple of cases that vary by .001" from one side of the neck to the other. Maybe that doesn't matter, but it's conceivable that .001/.013 = ~7.5% difference in thickness from one side to the other *could* be detrimental to starting the bullet off nice and straight.

Good brass properly used lasts forever, so it's worth the effort to me. You won't catch me touching brass for my AR. But for F Class level accuracy or better, I don't see any reason not to other than the cost of the tools, which is not insignificant.

Buy once, cry once... I bought the new 21st Century lathe, it is easy to use and produces a very nice finish! I’m anxious to try their trimmer/end prep tooling which according to John will soon be available.

I use the 21st century kit as well. Top notch equipment. If a person doesnt want to foot the bill for the lathe setup (like myself), the case holder with drill adapter is just as fast. I free float the Turner and drill with my hands.

The answer is YES. But you're doing it for the wrong reason.

When I first started reloading I was lead to believe that concentricity was essential for accurate hand loads. Then I learned about the Holy Triinity of precision hand loads:

1. Powder,
2. Seating depth
   
3. Neck tension

Concentricity was not mentioned. I have since learned that concentricity is a by-product of good brass prep and process but not a goal.

The real reason to turn necks, or as I prefer to call it: neck uniforming, it is part of controlling neck tension. Common sense tells you that if have significantly different neck tension you are not going to have uniform neck tension and therefore uniform bullet release. Uniform bullet release will result in a more uniform velocity (lower ESs and SDs). This will not be of much help at 100-300 yards but it starts to show up on target the further out you go. In F-Class, at 1K yards SDs of 5 or less over a 20 shot string are essential.

Here's a tool that makes the job easy and for around $100 it is the best value out there. You can spend more, but you wont get a better one.

Hello Joe! I have watched you grow from a neophyte loader to one that can dispense valuable information! You have come A LONG WAY! I like that immensely!

does Hornady offer a 40 degree cutting blade?

So that means the same thickness all the way around,correct?

 

[josebd]

I measured my 223 and 308 shot brass outside of neck and loaded,a
Both had about .010 clearance
I just want to skim the brass so there the same Thickness all the way around

Won't get better one? Have you ever spent more money on a higher quality neck turner? I assure you they are better.

I would not recommend using a neck turner that didn't allow the case and turner to float in alignment. Cases almost never run true when spinning in a shell holder. Jamming the case onto a rigid arbor to make it run straight for turning is no good in my opinion.

Watch the video at time 3:15 when they are turning the neck and pay attention to how that case 'pops' off the arbor and is wobbling around. That case is under stress and the neck is not being cut properly.

No way would I use a neck Turner that didn't allow me to float the case and holder. Cases almost never run true when spinning in a shell holder. Jamming it onto a rigid arbor to make it run straight for turning is no good in my opinion.

Yep,your right

Jose,

To answer your question. Yes, you are correct. Shoot straight!
