Well I been thinking about turning my necks. I have not for 52 year's what I learned is the diameter is the same for both an tension so any extra brass is to the outside of the diameter

What's needed is a neck turner that does both the inside and outside of the neck at the same time. And one that doesn't cost $2500 bucks because they think we're all morons.

I agree with you on both counts. I am also starting to think neck turning is not even necessary unless a person has a custom rifle or a very tight chamber. Thanks for watching and posting.

Good video 👍 one thing I noticed was the target moving with the wind, the outliers seemed to appear when the wind picked up and swayed the target a little

Yeah, that wind can be terrible out here. I watched the video carefully myself while editing but did not see a good correlation between the wind gusts and outliers. I suspect it did effect the bullets though and likely effected all the groups shot that day. Thanks for watching and posting.

Did both batches have the same neck thickness? I see the control group had a variance of .003 and the turned had a variance of .001, so i assume the turned cases had thinner necks than the control batch? You mentioned keeping neck tension the same, but the data said the neck o.d was the same in both batches. Seems like a thinner neck with the same o.d will have a lower neck tension. I appreciate your content, I just found your channel and have only watched 2 videos so far, but I expect that to change quickly. I have custom precision chambers but have never turned necks, trying to decide if it will take me to the next tier of accuracy. Thank you again for the content, only in this for a year now and still so much to learn.

Hello and thanks for watching. After turning, the two batches had very similar neck thickness but note there is still variance. When turning necks it is very important to pay attention to the shoulder. Don't cut into it but also don't stop well before the shoulder. If you do, that will create a donut inside the case neck differentially affecting bullet tension. For factory chambers I have found neck turning is not needed. For your custom chamber you MIGHT benefit from it. I would contact the smith or company that made that barrel or did the chamber work for you and learn if they recommend neck turning. If you do turn necks, the Hornady tool is OK, but there is a newer neck turning tool that simultaneously cuts inside and outside. It looks like it does a great job and if I were to buy another, I would probably go that route.

I am still researching which tool to use. Seems most people prefer the 21st century cutter when the idod is out of the price range. Thanks again for the info and content.

@@joshuaahughesify I completely understand that decision. 21st Century makes excellent tools. I have a number of their products and never disappointed.

A lot to process there. Is there a chance of a barrel swap in your rifle's future and if so do you have a small handful of brands that you are considering?

Hello Aaron, Good question. About a year ago I started looking into a new barrel for the RPR with the idea that it will reach its end of life. But upon studying velocities, etc. (and the fact that I only have 1400 rounds through it now... I keep an exact record) I tabled the idea. Today, If I change the barrel it would not be that I shot it the current barrel but rather that I want a better chamber and throat/leade. I am open to suggestions on brands. Thanks for watching.

question: initially my neck wall thickness on my PMC & Rem. cases were inconsistent but as I reload for say the 3rd or 4th time the neck wall thickness appears to be evenly consistent all around. Am I experiencing something or am I just imagining whats going on and maybe should get a better calliper ?

That is hard to answer. Brass flows during firing and it is theoretically possible that repeated firing, case prep, etc. could effect the change you are seeing. I am measuring case neck thickness with a Mitutoyo 115-313 tube micrometer. If you are using a jaw caliper that may explain the change also. The take home message from our test is that neck wall thickness needs to be highly variable before we see an effect on precision. Thanks for watching.
