For those who are new to reloading, maybe a few who have been doing it for a while. Not all bullets are created the same, use a micrometer and check the diameter of the bullets you are loading, there is a difference of a few thousands between manufacturers and in some cases bullet to bullet in the same lot. I am not a professional shooter, just been reloading for many years and have spent hours and $$$$ getting good groups out to 1500 yards. Enjoy the hobby, if you don't enjoy reloading, you will probably end up with less than quality ammo.
one important thing that is missed in this video is making sure the wall thickness of the necks is the same in each cartridge. differences in wall thickness will affect neck tension.
Noz W For 1 thou tension I size to -.002" from loaded round then put an expanding mandrel through which will push out 1 thou giving me -.001". brass is springy and whatnot but this helps push the neck imperfections outward vs just using a -.001" bushing which would push them inside the neck. for 308 win, expanding mandrel is .307, turning mandrel is .306 so with these you can get 1 or 2 thou neck tension, for 2 thou you would use a -.003" bushing followed by the turning mandrel.
Ilearned my lesson yesterday when neck sizing 7mm-08 to 243. I was using new Hornady brass and after I resized the neck I tried to load the first round. The neck collapsed and I sat there scratching my head. I measured the inside diameter if another piece and found the hornady brass is thicker than I thought so it was way too small. I resized all the brass necks again with a neck sizing die and problem fixed perfectly. Always measure the internal neck diametrs from now on.
Shouldn’t he have been measuring the inside of the case? Two thousands on od doesn’t accurately apply 2 thousandth on the bullet if the case wall thickness varies . Just sayin...
Both are equally important. You want a good seal around the outside of the neck while the round is in the chamber. You also need a good neck tension as well, too.
Wouldn’t you want to measure the wall thickness and double that , then subtract that figure from bullet diameter. The difference should be the tension. Of course the wall thickness has to be the same all the way around to be consistent. Plus, annealing makes a difference too.
As always Aaron, your vids are first rate ! I have been shooting and hunting for 47 years now and I love to keep learning. Your dedication to long range shooting and everything to makes it work is teaching me a ton. thank you !
I see the Hornady Lock and Load system on the your press. I absolutely love them and am glad I put them on my RCBS press and dies makes things a lot simpler...
Best way is to buy a match resizing die that shrinks the neck to proper size without having to crimp. I have found Forster dies do this perfectly to produce good match ammo. I do not mess around with bushings, but, if you are OCD, just go ahead and get the bushings.
For correct neck sizing use a Lee Neck SizingDie.My rounds usually are within .001 of each other, ( If I do my part). No coyote or deer will ever know the difference. None of them has ever complained. SHOOT SAFE!!!!!!!!!!!
The ball isn't really opening it back up much to be honest, it's doing most of that on the way in, and it barely touches on the way out, i dont even run a ball in mine, and most people now dont run one either, this video is old
Audie, I don't know if he replied, but I've taken deer and coyotes w/ AMAX no problems. If you look at his gear it's ALL Hornady. I'd think that's a sponsorship deal. I could be wrong though. Berger Hybrids and VLD hunters in my experience will hammer on deer. That's in my friends .260
I mic all my drass and turn inside and outside of it to insure all my drass is the same neck wall thickness, I use Redding FL bushing dies for my hunting loads as I have witnessed ppl who just neck size have feed isues in the feild. I allso use Redding custom shell holders in conjunction with the fl bushing die to insure that I have the minimum amount of shoulder bump so I dont overwork my brass . Good video and I agree enough Hornady on bench to indicate sponsoreship . My bench is a mix of whatever works best .RCBS, Redding, Foster and yes some Hornady to but not their dies , never tried them , how are they
Hornady has great engineering & sales teams, but their products are subbed out to China to be built. Don’t use Hornady dies for precision work. The only thing I will use my hornady l&l progressive press and hornady dies for is practice pistol rounds. If you see rust in my reloading shop you know you are looking at a hornady product.
Rather than ordering a custom die and bushing you can just buy a Lee Deluxe die set which will come with a Collet Neck sizing die which is adjustable for any chamber. Also they will make you a custom Collet Die for Wildcats all you need to do is send them 2 fired pieces of brass and sample bullet.
Of course, to even know your neck wall thickness, you need a tube Micrometer, otherwise math alone won't work. It also helps to know and have neck turning equipment. Bolt actions like 1-2 thousandths of tension. Semiautos need tighter tensions (if you want your bullet to stay in place during cycling). It's even better to use a press with a Ft-lb gage on seating pressure (eg K&M or XXI century hydro press).
If you have a Forster FL die, that company will hone the neck to your specs (.0005") if you send it to them. Some adventurous people may even do this themselves with the help of Blind-hold laps, lapping compound and gage pins. I'm thinking about giving it a shot so I can have a non-bushing FL die for my 280 ackley that has custom neck tension.
Aaron, when I use calibers I get a much smaller reading than say a Mic, I pull the calipers real slowly over the neck, and I can feel them grab at the edge of my calipers. I use that number as it measures up w/ my RCBS mic. Then I get a redding neck bushing that's 1000th or 2000th smaller than that. Does that sound about right? Thanks
The larger the diameter the more area in the neck the bullet is against. Seating depth is also important. So 0.002 in could be universally true no matter the caliber. Friction is what is produced. But the neck tension will NOT be the same. 0.002 in strain is a higher percentage strain in a 22 caliber neck than a 338 neck. Why? Brass is a linear elastic material. This means stress ( neck tension) is directly proportional to strain ( % elongation) or diameter increase. What is most important is 1) the neck tension is not too much or little and 2) it is consistent round to round. We don't want recoil reseating the bullets in the magazine. This means keep the seating depth +/- .002 and the elongation +/- .0001 or an order of magnitude less than the elongation itself. Most precision dies will do this but keep checking with your micrometer!
Let me point out your deliberate mistake. When measuring the neck size you must measure from the inside NOT the outside diameter. If you measure the outside diameter you are also measuring the case as well - this is wrong. You must measure the inside of the neck as that is the true measurement of where the bullet will be seated.
Little tough to measure the inside neck diameter with the bullet in there. His point was to compare the outside diameter without and then with a bullet seated, looking for 2 thousands difference. I thought it was pretty good advice.
ohherrofriend : actually you measure the inside diameter before seating the bullet. Yes neck thickness varies from manufacturer to manufacturer. The diameter of the bullet does not, which is why you measure the internal diameter not the external.
F53802 if you're worried about neck thickness variation then go ahead and neck turn your cases. That doesn't change the fact that a 2 thousands difference between an outside diameter of a SINGLE case before and after seating a bullet is a fast and accurate way of gauging neck tension on that ONE case, much more so than measuring the inside diameter of the case and the outside diameter of the bullet and guessing at what frictional and tensile forces are doing.
Not 100% true. Couple different ways to accomplish the same thing. Method #1 - caliper around neck with bullet seated .243" - .003 (desired neck tension) - .001 (brass springback) = .239"; Method #2 (method you're stating) - .015 (neck brass thickness)x2 = .030 (neck brass) + .213 (bullet diameter) = .243 - .003 (desired neck tension) - .001 (brass springback) = .239". Both came up with the same number. So as the neck size bushing is the diameter of what fits INSIDE of it, you have to add the brass to your equation which both method 1 and 2 do.
I'm still a bit fuzzy on how you can get the correct neck sizing while using an expander ball. It seems like it would make more sense to use the expander ball, then remove the expander ball and run all the cases though the die to set the correct neck size. Am I missing something here?
without an expander the resulting neck hole is dependent on case wall thickness. an expander pulls the neck hole to the size of the expander ball every time
Yep these are perfect and thats what I'm using for my final "neck up" operation. I'm using hornady bushing die to neck down for instance on a .264 to .262 and then the TiN coated Sinclair neck mandrel bumps it back up to .2635 giving me about .001' neck tension which for what I've discovered is plenty
Nice graphics work mr. video guy. On neck tension; I see significant variance in neck wall thickness (Hornady brass) so I prefer to turn my necks on new brass for more even neck tension. How much downrange benefit do you think neck turning has?
The Lee die is all you need. They patented their style of die. All the other manufacturers use those stupid bushings and expander balls that cause more runout and are harsh on the brass. Lee really made a homerun but the others too want a piece of the cake and will tell you everything so that you will buy their expensive stuff.
Hi> help needed. Im using a hornady progressive press with RCBS die for my 223. ive been having issue after issue. i got my brass from the range from the person next to me shooting 556 ar 15. this is once fired brass. I feel like my neck tension it too tight. is that possible? i tried taking the bullet out with the hammer bullet puller and it to like 40 whacks when the ones from the store come out with 2-3 hits. Problem 2... during resizing the brass i have to tweak it to go pretty far down the brass in order for it to feed into my remington 700 bolt action rifle smoothly and allow the bolt to lock. im just not sure if its the die, if the die is missing something i need or what to do
Elad, couple things I would guess without knowing all the details. Sounds like the neck tension was probably way stronger than what it needed to be. And yes, it most certainly is possible. Imagine taking a set of vice grips and giving them a half crank before clamping. It's pretty easy. Now take those same vice grips and crank it down about 4 times and try to clamp them. Secondly, from what you said, I wouldn't worry too much about having to tweak the brass in order for it to fit in your rifle. Every rifle is different. Additionally, you said the ammo was once fired ammo. I wonder if they're once fired reloads, the type of brass, etc. A lot of variables really.
Poorly done explanation for most of the reasons people brought up previously. Expander button diameter, or not even using one, was barely mentioned, but cannot be ignored. There are far better and more detailed explanations elsewhere. That, was pretty hokey,
Thank you for your videos they are very helpful I have a problem I hope you might be able to help me with I have neck turned some 308 rem brass I now don’t seem able to get enough neck tension for the projectile with out over adjusting and crimping the shoulder.i am using a Hornady die ?
You could use a Lee Collet die to necksize after body sizing. You can custom order or polish down the Lee Collet die mandrels to achieve any neck tension you want.
Sometimes you just don’t need the accuracy. An example the dies are sold by the thousandth .326 .327 .328 so based on your caliper being accurate to .001” if you get a .3275 do you go up or down? If you knew that was exactly .32755 does it change your mind?
Arron , AMAX ? Are you going to test these on game ? Are you moving away from berger ? I have heard some great things about the and some not so great then again same goes for the VLD.
IMHO If you are not turning your necks you shouldnt eff around with bushing dies. If you are not turning, size with a regular FL die without expander ball then set neck tension with a 21st century expander mandrel sized to whatever neck tension you desire .002" IMO.
Yes but I'd listen to an hour of that music just to be able to read the pissing match betwen jon gibson and crosstimbers2. It is by far the best one I've seen in a while.
I need to get a case wall thickness gauge. I'm using an RCBS gold medal neck sizing bushing die and I can't get 1 MOA out of my rifle and it is a Savage realistically shooting 2.5-3 MOA. However, with my full length $40 dies and another rifle, 1/2 MOA is easy. And with milsurp crap, 0.9 MOA is easy. And in my 223 *mossberg mvp* with its action made of gravel and trigger made of pencil eraser using Wolf Gold taiwanese M193, 1 MOA is a maximum 5 round group size. That gun is my definition of 1 MOA as that's the worst it will shoot over the course of an afternoon. But the Savage using hundreds of dollars worth of equipment firing cartridges that cost over 3 dollars a shot, I'm shooting minute of beer can. Reloading sucks.
+spraynpray Something is seriously wrong with your rifle. I would send it back to Savage. Neck tension is not going to fix a 3 MOA spread. Once your rifle is shooting well, (sub MOA) which a Savage should do easily, I think reloading will be much more enjoyable for you.

Don’t neck size. Full length size every time for consistency throughout. F class shooters never neck size only.
