Take a look a Clicksprings videos if you seriously think the 7x14 isnt capable of precision work. Only non machinists would claim it isnt. The 7x14 (wherever you buy it from) is quite capable, and is as precise as YOU are. Funny video....but c'mon guys.
lol me too...when he said "High precision lathe" and went to harbor freight... I was like ok buddy but hey I'll keep watching..... But then...when he said use a 3 jaw because they're more accurate than a 4 Jaw....when any of the best 3 jaws will inherently have .003" IR....Ok this guy may have a couple lathes but doesn't know much about machining. THEN....when he cranked down on the bullet...with two hands distorting the jacket obviously....instead of using a collet chuck....I was like.....Ummmm What THE? And all the time knowing a projectile at supersonic will have air seperation at the base and the base profile only matters upon the subsonic transition phase....I was like Ok I gotta keep watching to see this guys BS claim on a 1000 yd group. 5/8" But even then....my engineering mind was still trying to figure out the reason for the obvious results since we all try different things to Eek that extra .001" out of our groups. Bore lapping, bullet coating, muzzle crowns, blah blah. BOOOM freakin got me....April Fools. Very well done.
@John Beige YOU NEED A COLLET FOR THAT JOB ON A GOOD QUALITY LATHE BUT ON A PRECISION MAC-IT WOULD GIVE GOOD RESULTS THEN WEIGH AND NOT GET THEM OUT OF ROUNDNESS OR DEFORM .MAKE THEM FROM SOLID STOCK AND USE A CNC THREDING MAC WITH COLLET --MAKES A DAM GOOD BULLET IF YOU SET IT UP RIGHT THE HOLE WILL STABLES THE ROUND--- A DAM GOOD MACHINEST CAN MAKE A DAM BABY HELLO--NOW THAT A DAM GOOD MACHINEST THOUGH
I love this. As a full time machinist and a machine shop at home. HF HIGH precision lathe ??, 3 jaw chuck with no jaws ??, crank down with both hands ??. I would imagine within the first few minutes people were ready to rush out to HF and spend money. On a serious note, Sierra designed their precision bullets with a small hole in the nose and boat tail. A small hole/cavity at the base. MM...maybe Erik has stumbled onto a top tier super secret, known to only those at the highest level, revealed to them by visitors from planet X0. A T-Shirt would be nice.
I wanted more precision than your lathe provided so I chose and Harbor Freight 3/8" drill with a hand chuck. It was a 3 jaw too so I figured it would be really good. My rubber palm gardening gloves held onto the spade bit really well when I gouged the base of the bullets out.
I really knew something was up when you sd the three jaw is the most precise there is. I am watching you do this and I'm thinking how in the crap does that make a difference. You had me all the way to the end Good one!
I'm surprised that you didn't tell us about powder grain reshaping tools. Those things are amazing. I'm glad that your mentioned "deform to perform" though. You're very generous with info.
I like to drill mine completely through. It lowers the weight so the projectile falls slower (better for long range) and the tube shape helps it stabilize in the air.
Totally had me until the end when you mentioned it. LOL I should've known when you started off by saying the HB lathe was a high precision lathe, then talking about how a four jaw chuck wasn't as good as a three jaw. Finally, I kept thinking about how the yellow dots covered the holes, thinking he could've just put dots on the target, but your reputation kept me from questioning it. GOOD ONE!
This actually makes a perfect seal against the rifling during powder explosion 🤔 thus aligning the projectile in a very defined concentricity while jumping even into an eroded barrel 😳
That was good. When you started to crank down on the 3 jaw, I was losing you there (3 jaws marking the bullets? hahahha). Then the 3/4" dots over the target, ya, sure, all bs. The ending is the best. That was too cool, great sense of humor.
Awesome Erik. It reminds me of some of the early cast bullets that had a similar concave butt of the bullet. I always wondered those cast bullets, although they were very fat with poor BCs, wouldn't enhance the accuracy of the shot.
You had me til you showed the HFT lathe...at that point I figured out where this was headed lol. For some reason it did not occur to me that it's 4/1. Nicely done Erik.
Any machinist know it was a joke when he said a 3 jaw is better then a 4 jaw. And yes i can see guys now drilling their bullet out and thinking they will be shooting as good as Eric lmao.
I’m calling B.S. on the three jaw. They come with the lathe because they are cheaper to make. For precision applications use a six jaw or a collet. Four jaw chucks are used for awkward to hold parts. Yes you can get precision out of them if you want to take the time and indicate them every which way from Sunday.
Couldn't wait till the end of the video to try this it worked great All my one shot groups out of my 6.5 creedmoor measured 264 best consistency I've ever had
I found if I do this process Erik shared plus I shoot a perfect 0.51875" group, at 1k yards even if move my reticle I still end up with a 200-20X score. It's like impossible to miss!! Neck sizing was the other key, and using battery acid to clean my grooves. That was prob the hardest part, only getting the acid on the groove portion.
I will be honest, you got me for a few minutes !! I was thinking maybe the rear of the bullet will fly differently if there is a void, but then I thought, wouldn't the bullet manufactures know this, Eric isn't that smart :)
Catching up here as I just found your channel the other day and decided to start at the beginning. As soon as you said the 3-jaw is the most accurate I figured something was up.... then noticed the date :)
Oh man you really had me Erik dang you should have seen what I was really going to write for a comment. Good one Erik stay safe God bless and have a great Easter weekend...
Bruh. The people that watch this in a few months from now, and don't check the date it was published, is going to be hilarious. But in all seriousness, I was genuinely curious to see how these shoot... Once the gas entered that simple, it would probably blow the skirts out lol
By the way, I wonder what those Bullets really did. It would be interesting. I remember you concrete slab April Fools joke. You are real good at keeping a straight face.
Actually here's the funny thing. Americans are years behind. The Italians have a patent on what he's joking about and has been used successfully. So to answer your question, you have to do it with longer bullets but it does perform and theres several tricks to add to what has done. Just it's not financially acceptable for production use.
Very funny Eric, but now can we all bow our heads for the poor little freedom seeds that tragically lost their chance to fulfill their destiny and hit the X ring 😢🙏
Holy Crap! You're the barndominium guy! You shoot too? Heck even more of a reason to get a quote from you when I get ready to build. You have some great barndo's.
Assuming bullet get rear presure and swells rear part of the bullet to expand a tight fit in the barrel as flys out to the end of barrel forming a prefect fit. Would be wise to set up gel block to caught bullet to see how it formed at that distance. Very interesting and even more interesting to see what the bullet looks like after being shot. Kiitos to you dude
I just watched this 10/24/22 I'm thinking to myself the whole time, WTF? You gotta be kidding me. What about concentric balance, what about the weight of the five projectiles, what about the CG, ect...Then near the end I'm like this guy has the driest sense of humor and is just F'ing with people. Good job!
You should work around the chuck and tighten each jaw screw equally. You should also turn the jaws before clamping the bullet, to minimize concentricity and runout.
He said, "high precision & Harbor Freight" in the same sentence. It took me about 5 mins to stop laughing. OMG, that was funny, and it got even funnier as he went along. :) Very good one. :)
