This video covers two topics: essential case measurements and how to turn case necks. Both will help produce more uniform brass and get us one step closer to putting two bullets through the same hole.
As noted in episode 1, keeping an accurate journal is also important. To help our viewers, I have posted a check-sheet that you can download and use to assist you to become a better reloader. Just visit our DropBox at www.dropbox.com/s/z936kfgl11t...

I dip the whole case neck into oil as it seems quicker. I also push the case onto the mandrel a bit then lock it down as it seems to help with the wobble.

consistency equals accuracy. never a true word spoken, since using this method my shooting groups have improved dramatically. many thanks for sharing..

I like your approach to first start determining the "gold standard neck thickness". Good tip to keep brass cool with lubricant...I don't think heating would cause brass to become brittle, but it would cause the neck to expand and thus inconsistent cutting depth may result..shallower cuts for cooler necks, deeper cuts for hotter necks. An expansion of half a thousandth of an inch would be bad... Before neck turning, all cases need to be consistent in terms of case length, so trimming each case to the same length may be an important step. With neck turning, cuttting into the shoulder will weaken a case. But not cutting the entire neck all the way to the shoulder will cause an external "doughnut" that gets pushed inside the neck when the case is fired (and the case neck and shoulder expand to the chamber wall). That internal doughnut can then cause accuracy problems. I usually fire-form cases, resize with no expander ball, then use an expander mandrel so the case neck can be expanded to perfectly fit into the neck turner mandrel in terms of tightness. After using an expander mandrel, the internal dimension of the neck is more consistent and more concentric. Then neck turn so the external dimension of the neck is consistent.

Great video (as always). Whenever I watch "how" to do something, I always wonder "why" it is needed. I was wondering how the diameter of the outside of the neck affected the performance. You explained that in the last few minutes and it made sense then. Thanks

I have really enjoyed your series. This is my brass ranking: 1. Peterson 2. Alpha 3. Lapua 4.Norma 5 Weatherby

@sdkweber Год назад

Thanks Jeff. I have been trying to buy some Peterson brass for quite awhile but cannot find it in stock. I would really like to try that brass. Have you used ADG? I found that is darn good also.

@Jeff_Seely Год назад

No I haven't tried that one but I hear the same as you. Let me see if I can scare up some 243 Peterson. I might be able to send some...

@sdkweber Год назад

@@Jeff_Seely Thanks Jeff, I have added my name to several online stores selling Peterson and hope in comes back in stock soon. I think I will be able to get some sooner or later.

@timothylandon001 6 лет назад

After watching the case wobbling in the clamp before going over the mandrel, I have to wonder about concentricity. It looks like the case may be being forced hard to the cutting blade at times, then forced away at other times as it completes a rotation. I note similar issues with plenty of folks using case trimmers. I will suggest putting the case over the mandrel first, then tightening the clamp where possible.

@sdkweber 6 лет назад

Hello Tim Thanks for watching and posting and for the tip. I would like to try this next time I turn necks on some cases. Not sure this machine will allow it though as the shell holder requires the shell to be slid into it from the side. Once it the case neck is on the mandrel I am not sure there will be enough play in it to allow it to slide in.

@tyronekim3506 5 лет назад

You make a good point about case wobbling. Wobbling is usually an alignment problem between centers being not concentric - center of mandrel and center of case clamp, case neck center and case body center, or combinations of that. I have a hand crank on my case turner, and I'm careful not to put excessive amount of downward or upward pressure on the crank that can cause the center of the case clamp to shift while I'm turning the crank. If I were to use a power drill to turn the case, I would have a fixed support to support the body weight of the drill. Good luck

@marktroy66 7 лет назад

Good video. one suggestion. you have some misinformation. when talking about heat in brass, it does not make brass brittle or hard. similar to copper, Brass hardens only through working. In the case of cartridges, after a case is fired a few times it becomes harder. this changes neck tension. Annealing uses heat (700 F) to soften that brass again to make it uniform piece to piece. thus creating more consistent neck tension. Another bi-product of annealing is dramatically improving brass life. In terms of neck turning, heat isnt good because you can end up with galling on the arbor. however, it would be very extreme to get it hot enough to anneal the brass as 600-700 F on brass has a very slight glow in the dark. Anyway. I hope you dont take offense. But Its very important to understand metallurgy of brass when reloading for precision and long life. Best regards. Mark

@sdkweber 7 лет назад

This is good stuff Mark. Thank you for the post and you have made a good clarification. In effect, heat softens the brass (annealing) and work (firing, etc) hardens it. In regard to neck turning then, the lube is more for the cutting pieces (steel) than for the brass.

@marktroy66 7 лет назад

"In regard to neck turning then, the lube is more for the cutting pieces (steel) than for the brass." No not really. Lube does a few things in neck turning. Maybe the most important is it lubes between the mandrel and case neck. If the fit between those two are very close, as the neck heat, like with any material, it expands. as it expands that fit becomes closer and closer until in effect its an interference fit. When that happens you can get galling. meaning the brass and the steel of the mandrel will try and fuse like soldering. the lube reduces the friction and threes less heat propagation. Also when cutting any sort of metal, metallic or not, lubrication gives better tool life and increases surface finish.

@sdkweber 7 лет назад

Thanks again Mark, This is very good information. As you saw in the video, I do lube both the cutter and the mandrel (even if I did not appreciate all the details of why this is important). I realized it is important and now have an even better understanding of why.

@DLN-ix6vf Год назад

Good Vid. well explained thanks One question when you neck size any case the overall dia. will be reduced so I guess that means changing to a smaller bushing die correct.

@sdkweber Год назад

I no longer neck size my brass. Instead I full length resize using the Redding Competition FL Sizing Die. This takes a bushing that one buys separately. For my .308 I am using a 0.334" bushing. Just at the end of the case prep process, I expand the necks using a 0.3060" mandrel. All this gives me the neck tension "preferred" by my rifle/load (about 0.002-0.003"). The bushing you choose should be the size required for your load to perform well. Of course you don't want to size the neck down a lot and then expand it back out a lot as that unnecessarily works the neck and will lead to premature failure (neck cracking). PS- I also anneal my precision rifle cases Thanks for watching and posting. I hope this helps you. Let me know if you have a follow-up question.

@schofield0 5 лет назад

This happened to me but i found it was me not reaming some of the trimmed cases enough at the inside mouth and the bullet was catching on the inside roughness off the case also SCORING the bullet, pull a few heads and check them out see if they are scored .it was actually collapsing some of the front edge of the case causing them not to cycle easily. OR AT ALL

@TexanUSMC8089 5 лет назад

Run them through a neck sizer afterward and recheck the neck thickness and concentricity.

@tobiastorsi 7 лет назад

Great Video! Where did you get the measuring tool to measure the thickness of the Case neck? Thanks

@sdkweber 7 лет назад

Thanks for watching and posting. I took the gage from my Hornady concentricity tool, extra mandrels for the same neck turning tool, some thumbscrews, nuts, etc. from Home Depot and then crafted the rest out of wood using my drill press and table saw. It works Ok. I am thinking about getting a new gage from Sinclair though. I think that would be even better.

@tobiastorsi 7 лет назад

Thanks, will try that too

@sdkweber 7 лет назад

You are welcome. Good luck. One point to note is when you are drilling and positioning the spot for the gage make sure it is perfectly perpendicular to the mandrel. I ended up wasting a few boards before I got it right.

@dansteven1419 7 лет назад

I am getting about +/- .0005 after turning on my HCNT tool. I've noticed a bit of wobble while the case is on the spindle. What kind of variances do you see in NWT after turning?

@sdkweber 7 лет назад

Hello Dan What you are seeing is probably correct. +/- 5/10,000ths with this equipment. However, I am not noticing any wobble while I am turning these necks and in fact, a noticeable wobble would probably result in even greater variance than what you are seeing. Your shell holder is tight, right? I hope this helps. Thanks for watching and posting.

@PRACERZ 4 года назад

Very sweet vid ! A question for you. On some of my cases the neck thickness ranges from .015 to .0125. Now to get the best out of the neck should I take it down to .0125 or will it be too thin ? This is my very first time neck turning and some people say just cut till it’s all clean, but who knows at what thickness it will finish up at and what’s dangerous ??? Confused 🤷‍♂️ Any help greatly appreciated !!

@sdkweber 4 года назад

Thanks for watching. What cartridge is this for? .308 win? Knowing this will help answer the question you have. If you go too thin you may not have good neck tension on the bullet which in turn could cause some erratic performance in your loads. There are lots of variables so let's discuss this. BTW, how many cases do you have with the thin 0.0125"? I am a firm believer in culling anything that does not meet my specs. You could sort those out and use them for general shooting while reserving your best for precision work.

@PRACERZ 4 года назад

sdkweber thanks for the reply. Right now I am dealing with a bunch of 2X fired .270, in Nosler and Hornady.

@sdkweber 4 года назад

@@PRACERZ I have noticed Hornady brass tends to be heavy/thick. I like Nosler brass better. According to SAAMI specs your .270 should have an outside neck diameter of 0.308", with a 0.277 bullet that leaves 0.031" or 0.155 case neck thickness max. Those cases at 0.015 are pretty close to max. I would probably take them down a bit but not to 0.0125". How is your neck tension? Are you using any special neck sizing die to achieve a specific tension? Is this in a custom rifle with a special chamber?

@PRACERZ 4 года назад

sdkweber Have not loaded any of the neck turned yet. No custom rifles, just trying to make several guns the best they can be .

@sdkweber 4 года назад

@@PRACERZ I do not have custom rifles either. Some of the customs can have special chambers and throats making this more difficult. What I would do is seek uniformity/consistency. You might get good results by taking all cases down to 0.145 (or start by doing 10 of them... load them, compare them to previous results). You certainly hate taking off too much but you can work incrementally and take off a bit at a time (test/repeat). If you take off too much you can start anew with fresh brass. What is important is the consistency so the case (mouth) releases each bullet at the same pressure point and in a straight fashion to meet the leade and throat. I hope this helps.

@davidmethvin1705 7 лет назад

Your gauging case will reward you better than any neck turning you could ever do on caliber specific brass/ tight fit in chamber with .002 clearance for bullet release is best ( start a bullet straight it shoots straight)

@davidmethvin1705 7 лет назад

Volume measure powder not weight humidity affects weight on propellant / use weight to keep safe load charge on work up of target load then repeat that volume

@davidmethvin1705 7 лет назад

Use chronograph to get you load velocity consistent sub 10 fps is goal in variance / barrel temp heat will be your worst enemy as impact changes as does temp no long shot strings

@davidmethvin1705 7 лет назад

Check bullet run out for wobble in loaded case true it up / primer pocket depth cut same depth in all cases

@shawnmillett7448 7 лет назад

how are you liking that hornady neck turner so far? im in the market for one and have seen mixed reviews.

@sdkweber 7 лет назад

I am liking it very much. I used it to turn some .220 Swift brass recently and dropped by group sizes substantially. I am now pretty consistently at 1/4 MOA with that rifle. I will be running a bunch of .308 Win through it soon also. The only problem I had was with my .338 Win Mag cases... the arbors are too wide.

@sdkweber 7 лет назад

Correction, I meant mandrel and not arbors.

@jvwayne2 7 лет назад

Consistency begets Precision. Accuracy comes from Precision and an adjusted POI. Precision and Accuracy are not the same.

@sdkweber 7 лет назад

Correct. Good accuracy is highly unlikely without precision and consistency from A-Z. Of course one lucky shot is always possible but to repeatedly hit your target where you want to hit your target (accuracy) requires consistency, which will result in precision (small groups). This is what Maj. Plaster talked about in his classic book. Thanks for watching and posting.
