Neck turning and neck sizing ~ Seeking a higher level of accuracy! 

I've been reloading and studying it as a subject for 40 years. There is so much misinformation out there it's very hard to discern what is a bunch of nonsense designed to sell you stuff that it's unreal. This guy is a "straight shooter" and everything he's said in his videos, I've tried and he 's been proven correct. Thanks so much for the info.

Thank you very much for your layman's discussion on the brass information. I truly appreciated the way you keep the dialogue clean and direct without a lot of technical info. I learned a great deal on this video.

I've watched a few of your videos. Thank you for offering your years of experience in an easily understandable format! It's truly appreciated!

Thank you sir, great video! Still learning and will continue to!

Wow! Finally a very useful video, without background music or other BS

Some of the most accurate advice I've seen on RU-vid.

Appreciate your detailed advice. Been reloading since the early 1980s and can always learn more!

Thank you for this video. I've been reloading for years but learn something new every time I watch your videos. Just purchased a new savage in 338 lapua so I'm trying to step my game up in brass preparation. Which is why I watched this particular video. Thanks again!

For field rifles .. iv taken the advice of f class shooter and use a head space comparator after I have fire formed brass I simply use the comparator and bump the shoulder back .002 so I know I have great chamber fit and still functions excellent in the action ... also in regards to neck tension iv found removing the expander ball and using a expanding mandrel with .002 neck tension has also increased my SD and ES in loads 👍great info as always ... you always have the best no non sense information for rifleman

I really love these videos. They help expand my very novice knowledge in the area of reloading rifle cartridges. A topic that I am really trying to hammer down the most accuracy I can without going down the fiscal rabbit hole. These videos are a great value to me and thank you for them!

SOOO glad for your wonderful explanations that even "I" can comprehend! God Bless you too!

Thank you for another clear, informative presentation.

By far the most educational and interesting gun channel. Thanks for your videos I've watched them all!!

As always when I watch your videos I have learned something. Thanking you.

Great Video. I’m learning a ton from you sir. Keep them coming. Thanks

Thank you for your videos. As a shooter and reloaded for many years I am amazed at some of the facts you present (lubrication., cleaning, etc). You obviously know of what you speak. Thanks again.

Wow, your an awesome teacher, enjoyed it very much. God Bless you too:)

Excellent video I cannot say how pleased I am with this information is awesome thank you so much for sharing this.

Love watching this guy. I learned about reloading here. I had to watch about 100 videos and more from other channels, but this one I got the concepts down from. Thanks again Mr Blue. I dont know your name.🙂😂👋

Wow! I just want to say thank you very much for your videos and the kind you explain the things. Please go on like this 👍 And, merry christmas from germany 🎄

You are enjoyable to watch. No other channel goes this Indep

Excellent and very informative video. Thank you...look foward to more.

You are amazing. All that knowledge. Thank you!

Well done video! Thank you, Sir.

So good. Thank you!

Excellent video!!! Thank you. 😺

Thank you GunBlue, truly enjoyed the video. I'm getting back into handloading after 40 years. As a kid I used to reload for .222 and 30.06 with tong type reloading tools with my father. I still have the .222 Savage 340b from the 60's and still very accurate with factory loads. Looking forward to handloading for that again. Thank you again for the great info! Looking forward to to the next video.

Hi Sir, thank you again for sharing your great knowledge again with us. Since I have been watching your videos I have learned many things that have helped me in hunting and at the range. With your tips I'm getting sub Moa groups with sporting barrels,I couldn't be happier! I can't wait for the next video,surely I will learn something from that too! Thanks, and God Bless! Happy new Year from Mario of Sydney Australia

I’ve heard this explained many times but never this well and this understandable.

You always got great information. Thanks for sharing.

Thanks for sharing. Really enjoyed this video.

Fantastic video.

I learn so much from you. Thank you. I only wished you had playlist.

I really like your channel sir, I've found the information and advice very helpful. You are easy to listen to and follow. Thanks so much.

Awesome video packed with very usefull information for reloaders.

indexing the round in the chamber also helps accuracy. this video just touches the basics. Thank you Sir for the video. It took me back twenty years or more. Groups with a factory 700 ADL .112 - .124 , Cal. 243, 100 yds. Speer 100gr. square base bullet. This was seven, three shot groups. I never took more than three or four rounds into the field. Most of the time just one round in the gun. Never needed more than one.

Your video are great. I have learned a lot. Thank you.

Thanks for doing the opposite of most who just tech spec it till you cant get the idea or feel intimidated. Im a 26 year vet and i take great pleasure in leaving my ideas back and pay close attention to what I can learn and verify and i think i came on top. Ill be better informed and more responsible owner. On this side of the border shops just tell you what you need which happens ro be what they need sold feom whats available and pay no mind to your actual needs or expectations. I now feels surrounded by pseudo experts who in fact can only handle surface level scrutiny. Knowledge is power. Airborne!

thank you very much for these very great deeply imaginable explanations

Enjoying your channel. Respect from Aus.

Thank you again, Sir.

Very informative. Thanks, took me 30 years to get what you described in 30 minutes.

Great video sir!

great video.i learned a lot about reloading today. thanks.

Very accurate information ,this person is someone that is tested and true.

Excellent!

I got a lot out of this session. I did find that some one else recommended FL sizing for hunting for the same reason you stated. I also got a better understanding of some of the mechanics/physics of sizing. thanks

What a great video 👍👍👍👍👍

Fantastic video i enjoyed every minute of it. I can tell your a man that has an eye for accuracy just by looking at the alignment of your cabinet doors :-)

Very good video the more effort you put into your loading the better success you will have.

Thanks for your rifle reloading accuracy videos. This is where I am right now, I'm learning all I can about reloading ammo as accurately as possible. I am looking forward to "how to anneal video. I am doing it, but need confidence in my method.

Thank you Sir 👏👏👏

Outstanding 👍

GREAT video...subbed

Very good presentation.

Excellent video, thank you for posting. My only question during the whole video was on annealing. I'm delighted that it was addressed at the end and I look forward to a video on the topic.

I do not shoot in competitions, but I do hunt and have had numerous opportunities to shoot at long distances but am not a long distance shooter. I am interested in annealing, bullet seating, powder charges for specific bullets etc. I usually use Sierra match bullets, but have only done my reloading according to the RCBS manual. I fine your videos very informative and trustworthy. It is nice to see someone who actually knows what they are talking about.

You can cut into the shoulder area, and some neck turner producing companies recommend it. The neck shoulder junction is an obvious spot where brass flow stops creating build up of brass. Doughnut’s as an example. Lots of literature on the subject as well.

This is exactly what I needed. Unfortunately, I purchased dies already (including a full length resizing die), but what I needed was a neck resizing die for F class shooting. Thanks VERY much for de-mystifying all of the fine details that you discussed. Well done!

Excellent

Excellent.

I’ve found Lapua 6.5 CM brass to vary by up a grain. I sort them into heavy 50% and light 50%. Then the batches are within .5 grains.

Awesome FACTS !

Terrific.

I like all thing Forester.....great little manual lathe.

Very interesting.

I found consistency in set up using bag and bunny ears really showed my rifles accuracy potential. With this I can tell which loads are good or bad. My Mod 70, .223 I believe has a somewhat lose chamber though it shoots just under 1 moa with a particular load. I'd like to neck size only so the case has a snug fit and see what happens. I'll try sizing first because if you do two things you can't tell which one gave you the most added accuracy.

My last competitive bench rifle was a 30BR with a NO turn neck. Brass today has become so good (Lapua) that in score type matches neck turning has kinda become a part of history. The only guy I new that still turned necks was shooting a PPC and was a requirement for his chamber. All the other shooters in my area anyway were using 6 and 30BR's and no turn necks

What type of deprimming/primiming tool block do you use in your video ? Great videos by the way

Very good video. Nice bullet points no pun intended. And it looks to me like you use starret calipers. I'll be paying much attention to your videos sir.

Love your videos! I am just getting into the neck turning. For new and used brass steps, 1 form with FL die, 2 trim length if needed and then start the neck turn process. Am I missing anything? Thanks

Very good info...I'd like to know when specifically resizing cases to shoot one specific rifle, and that rifle being a semi automatic as in my case, AR- 10...How does one go about checking the fired case in this type of rifle?

I like the idea of the Lee neck sizing but what about bumping the shoulder?

When i shoulder bump my 22-250 case .002 - .003 in my Lee FL die the case stretch .005 - .006 thousands and always require trimming. Even without the expander ball in place the die stretches the cases excessively, so after 2 firrings they are over C.O.A.L.

Hi GunBlue, first off I'd just like to say that my brother and I love your channel! I was wondering if you're familiar with the S & W 686 plus, and if it would be possible to make a breakdown/cleaning video for it. Again, for all the time you've put into your current videos (especially the 1911 ones) thank you so much!

I strongly appreciates this lesson on case neck turning - however neck calibration without centered case body deteriorates the neck vs. the body concentricity! I have experienced (with a 30.06 brass) eccentricity of body vs. neck of 0,16 mm (6,3 thouthends of an inch) What is your advise to prevent or mend this?

Randy selby would be proud of these vids

Good tip to cut only the thicker side, not remove the thinnest side. When should neck turning cutting occur? Before or after annealing? Before or after full length resizing?

How do we now that the case neck center is on det case centerline? To achieve this we probably nede to cut the inside of the neck.

Thanks, again! I am impressed by the fact that you take so much time in answering questions. I read below that you do not recommend neck sizing for game loads. Why is that?

Really appreciate your knowledge and experience. Thanks for sharing that with us. Could you list the steps you use to create precision ammo (say for PRS shooting, not Benchrest) and what tools/dies you would use? In particular, I will be reloading for 6.5 Creedmoor. Have done more general reloading (plinking, target, some hunting rounds) in 9mm, .223, .204, and .308. Just confusing on the best methodology for precision loads.

It’s been a great debate weather Full Length Resizing or Neck Resizing only is best for accuracy. I’m a fan of Neck Sizing only, BUT this completely depends on using the same gun, and keeping you brass based on batch numbers. Any variation in components or behaviour has a negative effect on your results. When using the same gun the Brass becomes “Fire Formed” to that particular Rifle. Bullet Jump is another factor. In some circumstances the overall length can be quite an advantage, some enjoy adjust OAL to just tough the Lands, as in some cases a slight jump helps. You have to test heavily to see the advantage. I used to smoke the end of a bullet, (less power) haha. In other words when I came very close to the bullet with a match or lighter, and it would leave a very this coating of smoke on the case. I would adjust my die so I could barely see contact. That Remington 243 BDL enjoyed it. Had eight rounds in under an inch at one time. Ground Hogs/Coyotes etc. Be aware of brass flowing forward each time it’s fired. You might have to Trim your cases as well. Keep track of how many times a given shells being fired. There comes a time after chamfering that the neck gets very thin. I loved loading back in the day, in the last 15years I buy my shells cause I don’t shoot much at all anymore. I miss it and listening to you brings back fond memories. It’s enjoyable to listen to someone with so much knowledge! Thank you..

NRA highpower with the 223. I have collected a large variety of brass over the years, LC,Win,Starline,Norma,hornady and recently been shooting the Jagmann, which I think is great brass. I came to highpower from benchrest and am used to neck turning. All my necks are. 0015 so I can leave the same bushing in the die. I sort my brass by brand but use all the lots with the same load and prep. Uniform neck tension is the key in a semi auto and cut vertical group spreads in half at the 600 yard line and about the same at the 300. It's a pain to neck turn 500 pcs of brass but I have a lathe and a good setup and can do 50 in about 15 min. Don't go crazy with it especially with the lake city brass as some get as thin as. 009 in spots. Remember after few times of bumping the shoulder and trimming the neck will either have to be touched up with the turning tool or you have to decrease the amount of depth in the bushing. Feel free to experiment and have fun. BTW I don't use QL nor do I use a chrony. Never have, I load for group size. Younger shooters these days like to see the data in numerical form, I'm just fine seeing the data on the target and just ballpark the velocity.

Addendum; at the 19:17 mark, I answered my own question! I guess I was distracted! It pays to watch the video more than once!

Do this test with the LEE Collet Sizing Die. Take one of your new unfired cases and one that's chamber formed. If you can get an accurate measurement of the neck thickness in different places record them. Run each case through the LEE Collet die and remeasure all around the neck again. You will find that the die has completely uniformed the neck wall all the way around! No shaving required and no secondary tiny bottlenecks. Trimming is still required as required. Tell me if I'm wrong because I have machinist's tubing wall thickness Vernier micrometers in standard and metric and both tell me the die actually swages the neck brass to a uniform thickness just like a collet is designed to.

thank you

thanks, i noticed the brits using a faster method than we use. they seat the bullets with a arbor press with a pressure gauge on top. the rounds that are not in the norm will seat with a different pressure, they set those aside for plinking or fouling shots. then they measure and trim the thickness. that weeds out the time wasted on measuring each neck when you can do it while seating the bullet. any thoughts?

just a question if I may: What would be the minimum clearance between a loaded round case neck and the chamber neck? THis rifle(savage 112v in 22-250) is strictly for bench shooting. Fantastic video. I will watch it often. Keep up the wonderful work.:)

You said that the neck resizing tool from Lee is good as it works by press the neck. But what do you think abou the RCBS neck sizing tool with bushing ? do you have some tips for use it very well and avoid some stretching or others mistake ? Have good result with but get any tips from a good reloader like you ;) Thank you

Gun residue in wife's oven. Always a good idea. "Why does the turkey taste funny, Honey?"

Informative as usual. When a factory loads a projectile into the case neck, does that then make the ID of the case neck concentric? And then, once fired and neck turned, is concentric on the OD and the ID? If so, does annealing change this at all?

I use mixed brass with .223 reloads and can get 1/2 moa with my one AR.

This is the sort of thing I've been looking for. And what I was hoping you got into in your reloading videos, as I've been reloading for quite some time. My question is, why neck turn your brass, if you fire form and neck size only when you reload? If you fire form your brass, you're forming your case to that specific chamber. How would you have high spots if it's formed to your chamber? I went back and rewatched the part where you talked about neck turning. And from what I understand is you're trying to achieve concentricity. And that's where I'm confused. If you fire form, and neck size only, aren't you concentric at that point? Or are you trying to get even tighter tolerances? I've never messed with neck turning. But with certain rifles I own, I do neck size only. Mainly my varmint guns. I'm just trying to put this all together. Thanks

I get excellent accuracy using IMR 3031. I don't bother with weighing brass, 1/10 grain of brass takes up such small capacity while 1/10 of powder takes up much more space so it's not a 1:1 ratio by any means. Besides where is the extra weight in the casing, the head, wall thickness or oal ?? Once processed using different brass I can't tell any variation. Powder and bullet quality are the two most factors in accuracy that I've seen.

Could not disagree more when he says that you should "ALWAYS, ALWAYS" full-length resize for big game hunting. (1) You can chamber neck-resized rounds in your rifle before taking them hunting. Take care to keep your neck-sized rounds in such a way was they will not be exposed to dust or dirt, as even dust can change the way a round chambers. (2) If you're hunting deer with a bolt action rifle, you're very unlikely to need to chamber a second round anyway. Yes, it's a fine habit to chamber that second round instantly and instinctively , but how often do you really get a chance to take a second shot at that deer? (3) Even if neck resizing may only produced a small increases in accuracy, this is not the same as saying that increase is statistically insignificant or irrelevant. in fact, if you are hunting mule deer in open plains where longer shots are common, that extra accuracy becomes more significant as distance increases. Yes, that target seems plenty big at 100 yards or less, but what about 250 to 300 yards? Longer shots are more subject other accuracy decreasing factors, which would logically make the increased initial accuracy even more significant. I'd say that you should be aware that there is an increased likelihood of certain difficulty in chambering a neck-sized round, but consider trade-offs of your overall situation. Personally, the only time that I don't neck resize is when I'm not certain which rifle a round is destine for.

GunBlue490 Awesome information for us reloaders whom are ready for the next level of accuracy. I am currently reforming 308 Brass to 260 Remington. My question is should i doing the neck turning on the brass prior to reforming or after reforming the brass to 260?

Hello sir - you mention neck trimming just taking off high spot. As a precision long range guy (prs, bench) and a very anal ocd retired navy single seat fighter guy Im very (prob too) detailed. I neck turn to take off just enough to trim all way around neck. This gives me a set wall thickness that I can use to then try to set consistent neck tension. I always stay above shoulder. In your opinion is this acceptable from a safety standpoint? Example for 6.5 Creedmoor w Lapua brass I trim to .0135 wall thickness.

If your are using a neck sizing busing, how do you accommodate for variations in neck thickness?

Is the .223 brass from Lake City pretty uniform in weight~? Or should I be be looking to buy Lapua~??

will neck turning affect all calibers positively? So going from 6.5CM, 338LM that i do turn up to 375 Cheytac and 416 Barrett. How much of improvement should i see if already at 1MOA and 10 SD's ES 20.
