Thank you for providing an avenue by which I can utilize this tool without having to scratch holes in my scalp trying to figure out how to make it work properly.
I was hoping it would align the bullet alot better than that.. glad I saw this vid, to prevent me from buying it. I modified my case master to work alot better. 5/16 th bar stock and screws to hold down anvils and drilled out case neck thickness pin hole to adapt pilots an a set screw to hold it. I had two custom pilots made way back and checking neck thickness is way easier with the pilots then RCBS' pin they put on from the factory. I emailed a pic of it to show them I really wouldn't be much more to improve it production wise.
@@vaughnprecision up date..... I bought one. The bullet/neck spindle casting bore is off from the spindle shank diameter. The bullet spindle is fine if you set the right tension between the spindles, The neck spindle, for me, needs a custom pilot to give good readings. I will see if I need a custom spindle made to prevent any movement.
the neck spindle has too much clearance in the frame bore. I have a friend making me a new spindle and pilot. The bore in the spindle for the pilot isn't center either. I feel it's best to have this unit as tight as possible to eliminate errors and not blame sizing and bullet seating.
Had two neck spindles made with tight clearances with integral pilots. My runout is minimal and not blaming sizing anymore. Neck runs .005 to .001 bullet runs.0025 no need to straighten bullet. Polish inside head spindle to improve case to run straight
Another great video Mr Vaughn. I cant add much more to your video other than my comment below. Make sure the rims of your cases are squared and not dinged up, otherwise you`re wasting your time AND money on a hornady concentricity tool. A distorted case will add to your problems if you dont eliminate that first before trying to check concentricity.
@@vaughnprecision Have you had any tolerance issues or play in the hornady tool? I`ve yet to find one that is tight. Most i`ve seen, they have a ton of play in the shaft that is spring loaded. Put a round in the tool, zero it, now push forward and backwards on the black round knob. You`ll see the gauge move alot. I find that the hornady tool has way to much play in it. I was almost going to drill & tap it, put a pinch bolt in there to make the shaft tighter so i can get a more truthful reading. But i dont use the hornady tool only to straighten the rounds. I have a Redding that i use that do my final checks with.
@@vaughnprecision Good to know Mr Vaughn. I`ve checked a few out, and not a one of them were any good. The spring loaded end is wobbly. The best one of the bunch measured .005 movement. I would hold the movable end straight towards me (away from the gauge rod), zero the gauge, then push it straight away from me towards the gauge, like i was trying to push the gauge rod into the gauge so that i could get a reading on how much play there was. Think of it as a forward & backwards motion. I couldnt believe how much play was in the spring load end. And also being made from aluminum, it will wear, the more its used. I use a concentricity gauge every day. So i dont see this hornady lasting for a guy like me. I`m retired, so get to reload ALOT, lol. I am also a tool maker by trade. I`ve since built a much better one. LOVE your channel! Hope all is well my friend, take care ;)
I have a question for you. Do these tools make a substantial difference in semi-auto rifles. Will the force of hitting feed ramp change the correction on the round? Have you tested correcting a round, chambering a round, pulling it back out to see of it maintains the correction?
Most of the time these tools are for bolt action rifles. Semi autos are going to need factory crimping with full length resizing. You make an incredibly important point when the AR bolt carrier picks up the round and the bullet tip smashes the upper section of the barrel chamber a millisecond before battery. That has the potential to lose accuracy or make the round not so perfect.
Good video. I have an use this tool also. I even use it sometimes to check the banana effect on the case wall an mark the case so I can index it in my chamber. I also have the NECO concentricity tool. It is more capable of a lot more measurements.It's just harder to use for me at least.( Essential Tremors). If I could only have one, it would be the NECO. I've searched the net looking for how to videos on the setup an use of the NECO but haven't found any as of yet. Great job here !
Pard, if you just take the time to read the first half of Lee’s book. He dispelled concentrated and weight of powder. It’s like the Bible. It’s too thick too read, so you turn to the back half. Run a neck sized case into your rifle. It tells you where the bullet contacts the lease. Then you decide on a powder charge and then col. every rifle or pistol is different. You can define it in a ten round ladder and a ten round depth test. No need for extra cost
2 for 2, another excellent video. I like your presentation and your knowledge. Glad I stumbled upon your channel. I don't load rifle (or shoot), but planning an AR build in .300 Blackout...I think this tool will be quite handy in a year (or less). I like Hornady products a lot, so this will likely be the tool I eventually get. Will continue checking out your other vids. When ready to buy, will be happy to use the affiliate links.
I just bought this and was looking for hints on its operation. One thing I noticed is you didn't have the bullet near where the ogive meets the straight part of the bullet. It's near the front of the bullet, I think way too close to the brass. I've used mine on several 300WM cartridges now and find it to work great. Thanks for the video.
I've done some research on this gauge and I do not believe this gauge can work properly but maybe I am wrong. I do not take any credit for this information as I discovered this from another website, and will try to explain the problem here. Now this gauge will self center the cartridge from the bullet tip to the center of the flash hole. But if the bullet has runout, the self centering axial line will NOT coincide with the true axial line running through the center of the flash hole and the cartridge body/neck.
Do you find the Hornady concentricity tool will leave a ring / mark on the bullet end of things. I do have this tool and great vid by the way. I get a score mark from the spinning of the bullet so I would love to know which one will work the best ( I believe the kit comes with three tip holders ) I’m an FTR shooter that uses the savage target action ( my final decision to use this action was confirmed after watching you get yours in and start your build from it... I’m always checking your channel because the content is so relevant to what I’m doing or want to do.....great content keep it going ...thanks for putting in the work!
If you check NECK run-out with untrimmed brass, you likely will get the high and low readings of the thickness variations in the outside of the neck brass. Your bullet COULD theoretically be centered in the brass, but the brass isn't consistent in thickness. So, the best way to insure you aren't measuring brass thickness variations is to neck turn down to a consistent thickness, load your round, THEN check for run-out.
how does this help a .223? I mean its nice to have it look straight in a gauge but in real world shooting it might not do anything as the barrel corrects all that by the time bullet exits.
@@vaughnprecision So if you had 6" groups they are now 5.75" I shoot 1/2" using off the shelf from .204 and 450 Bushmaster 3/4". good enough for me. I hope my reloads are as good as factory.
@@Physics072 You're shooting at point-blank range at only 100 yrds. Try going out to 1000m and beyond. If you're merely plinking at beer-cans and rocks, there's no need for making your rounds super-accurate. It's more trouble than it's worth. And Bob, the barrel does NOT correct an acentric bullet. It's quite obvious that it does not correct an acentric bullet by the inconsistency of the point of impacts when using acentric (non-concentric) loads. That's why you are getting terrible groupings instead of 0.15 moa groups. But if you need to cleanly eradicate small vermin at 500m or more, or required to get consistent hits on an 8" plate or tango at 1237m, then making every cartridge as perfectly consistent and concentric as possible will pay-off big-time. This IS real-world shooting.... just not your world, yet.
@@SagaSeaCraft If you can shoot a mouse at 1000 yards hats off to you. I highly doubt it. Most people I see at the 100 yard range can make a group smaller than a football. 100-200 yards is all I can do in my area too many trees, out west no water no trees then yea maybe it matters. But shooting long range opens up many cans of worms in what stuff matters. Besides this small area you need a high BC, Stay super sonic out to the target, a huge issues is load consistency (no matter how perfect the bullet is) if your rounds vary by much in velocity it will be impossible to hit what you are aiming at as some will drop 10 feet short some 10+ feet long, left right etc. I think you need to shoot at ranges were all that is minimized which means no taking 1000 yard shots at game animals as too many variables to make a ethical shot. 400 and under is a good rule.
@@Physics072 There is likely no response that would ever be meaningful to you that I could write, because you don't care to understand what is being communicated.
Lee Patch I bought a professional mic last week, I'll be using that more often now. I also have a new wearable mic as well. Thanks for checking out the channel
Vaughn Precision thanks for replying. I think for my needs the Hornady May be what I’m looking for. I’m just looking for the ability to measure Case, neck and bullet concentricity and the ability to correct run out. If that is all I want is the Hornady the way to go? Hope you been doing well. I’m so jealous for your area to have you and not here in KY. We need a Vaughn precision here in my area. I am in the process of trying to find a GOOD gunsmith that can do the exact things you do in your videos.
