Richard Lee made an interesting statement is his Modern Reloading book. He basically stated that if the neck of the case is more than 0.001 inches less than the bullet diameter, the bullet serves as a conventional expander. He also said that a bullet does not make a good expander and would create excessive runout. In my opinion, since the brass used in your comparison test is random range brass, the data provided may be inconsistent due to other variables. It would be interesting to see this test done with a consistent lot of new, quality brass such as Lapua. Another useful aspect of this test might be to carefully remove a set of bullets after they had been seated and measure the inside diameter of the case neck. This would test the validity of Richard Lee's statement regarding the bullet acting as a conventional expander.

Something to consider if it's a auto loading is that if neck tension is light enough the projectiles will shift to touch when cycled therefore alter coal possible to a better harmonics position. Not that this is the cause of the smallest group but it does need to be considered. Seating depth with have the largest impact on group size a closer distances

Another method used by erik cortina is to use a bushing that takes it a little below desired neck tension, then use a mandrel to set the final dimension. You could just use a normal die amd then mandrel, but the purpose is to not over work the neck. I plan to try this soon on my new 20 practical. Also, annealing is going to change tension without changing the method.

HI Kevin, The runout measurements on the chart on the the seated projectiles. The video clip I show is historical footage from the original comparison. That said, if your brass is at all decent there is no chance that your going to measure .005" TIR on the outside of the case and the ID is going to run true. I am going to include other charts data in future videos to show this but I was try to do a raw comparison of bushing to bushing. If you use 3 different bushings with the same expander would it vary? Not sure but it is a question I hope to put data behind in the future.
@ShootingAndReloading2 жыл бұрын
@@BoltActionReloading I get what you say, and agree that we really don't care about the loaded or unloaded neck TIR. What matters is the consistent contact on the inside of the neck and bullet and hence suggesting devising a way of measuring any inconsistency there. A loaded bullet may have minimal TIR while making inconsistent contact with the inside of the neck. I'm considering a Redding type s full length bushing die with SAS bushings. Currently I'm running a Forster full length die, but with the expander ball removed, and then a Wilson mandrel to get the neck tension I want. With AMP annealing on every firing I'm getting highly predictable results. However... I've not found a way to accurately measure inside neck TIR. I'm learning every day and look forward to your next video :)

We are all learning, myself included. I am very frequently surprised by some of the results I get. I am going a little overboard in 223 probably because its a little cheaper to test and take what we learn here to other calibers. I have had good luck with your method as it is the same one I use at this moment for my target loads. Though as I go through this exercise, I may change. I feel that 223 is actually more difficult to load for because of the shorter neck, lower case capacity, (I am thinking that the variation in powder measurement is a higher percentage of case volume and makes lower ES/SD more difficult to achieve) and being forced to seat past the neck shoulder junction. I also was concerned at the accuracy limits of this platform but being able to get several groups 1/2 MOA or less encourages me that there is potential here. The factory I have tested shows ES 70+ over 10 rounds so every single option I tested is no where close to that. Glad you guys enjoy the videos!

Hi Gary. I appreciate that very much. Sarcasm was my 1st language, but I try to keep it to a minimum. I really wish I had a larger number of samples at each option, but sometimes the total number is getting out of hand. If you like the force graphs you will appreciate what's coming. (at least I do, but I am clearly biased.) how you size your brass changes these graphs, (I know shocker right) but correlating them to the accuracy is the hard part, but I am working on it. I spent 3 days the last 2 weeks researching how to write VBA code to automate some of the data processing tasks so hopefully the next ones I test will be faster. Back to your actual questions. I had pretty much abandoned my s dies until I found these bushings, but I have bought more so we are going to test it all. (eventually) SAC has been kind enough to provide the bushings, so I am going to try and get the testing results out there. I have not tried any of the new black nitride expanders from 21st century, I see they have a option at .001" and .002" under caliber diameter so I would get both if I made an order, then how many calibers? Have you used any of these new nitride expanders yet? I have had several folks ask, but don't have any feedback for how they work.

I really think this is due to the short action custom bushings only sizing half of the neck vs Reddings that size the entire neck. (all the way thru the bushing is the same diameter vs SACs bushings that only size halfway thru the bushing.) This is why you have to go 1 size smaller on SAC bushings to get the same tension, I am sure. If your data is correct then it must be helping groups I cannot argue that. But why is only halfway sizing the neck (approximately) doing that? I would love to see this test on good Lapua brass with the inside and outside necks turned /reamed for consistancy.

I ordered SAC bushings, when i reached out to SAC for their recommended bushing size and recommended mandrel size based on my loaded round OD of .292 i was told to order a bushing of .287 and a mandrel of .292 to obtain neck tension of .002 Thoughts? Should i be concerned about over working the brass? Again thanks for all you do!!

Each time you do a test with Short Action Custom bushings I try to buy some and they are sold out. One question, is there any bullet lube or lube in the neck that you use or is it bare metal? One F-class guy I watch says there should be some sort of lube.

I am going to do some neck lube tests. These are just whatever carbon was left after cleaning and brushing the necks. I am probably going to deep here in 223 with the neck tension stuff.

It's silly to refer to it as "neck tension" - it's like saying a car's MPG is 16 gallons (the size of the gas tank). We're measuring neck compression - we should call it that.

Compression is static. Tension can be dynamic. Tension is the accurate word.

@@BoltActionReloading LOL. I'll call it "neck tension" because that's the norm/standard. ;-( Seriously though, I GREATLY appreciate your channel and all your time and effort you put into this. Also, you're the only person I've heard discussing the application of reloading to hunting that has talked about need of precision to ensure ethical kills (that's why I load my own). Respect!

Glad you enjoy the channel. I pretty much only hunt with my reloads any more. I think is just more of a confidence thing. The more factory you test, the more I am surprised the accuracy that some are able to achieve with it. Not trying to sound like a snob, but I know I passed up an elk because there is no way I could make a ethical shot with the platform and ammo I had at the time. Spent so much money and 10 days of my life and came home empty handed. Never again. These days I would be 100% confident that I could make that same shot, but I haven't made it back, Yet.

Hey Guys, dear @BoltActionReloading let me have an ambiguous question for you, which is totally not clear for me and may put some new light on the subject. Lastly I found videos about this gauge kzbin.info/www/bejne/gn6yqWykd6d9sLs and it is also used for light "hammering" the neck. The thing is that the action is performed on fully prepered ammo, the run-out measurement is taken from body (not the neck) and the pivot is hitting the neck with projectile already seated. Am I missing the point of this device or in fact it's changing the bullet seat and can worsen neck run-our? What is the reason to hit the neck (with already seated bullet) and measure change on the body. Is it anyhow possible to improve total concentricity (to streighten the ammo) without any influence on neck and projectile seating? I decided to ask this question here because I believe this channel community have great knowledge and experience. I'll appreciate your help to understand the approach described. Cheers

Hello Sir, You ask a very interesting questions that many will disagree on the answer. I have not tested this type of functionality before because impacting the case on the most fragile part hasn't made a whole lot if sense to me. Though we all like small groups, this appears to possibly be more geared towards benchrest folks not to say you couldn't use it for what you like. Hornady's tool allows for something similar but I pretty much tried to fix my concentricity in my sizing die not after I had seated the rounds. If you decide to try it out let us know how it works for you.
