    Would there be a difference in bullet up or down in ammo cases.

  2. Cody Way on April 29, 2023 at 3:27 am

    If you compress the charge, with they grow?

  3. 6.5x47 Lapua on April 29, 2023 at 3:28 am

    Thanks! Now I have one more variable to worry about 🤣

  4. Lohi Karhu on April 29, 2023 at 3:28 am

    The clam would have done better, even, probably, if it was flat, the way you would likely pack then, instead of vertical?

  5. Tobias Torsiglieri on April 29, 2023 at 3:33 am

    AFAIK you shoot .284 Win. Is that correct? And which Brass do you use? Am getting a Barrel in that Caliber. Thanks!

  6. Angel Perez on April 29, 2023 at 3:33 am

    Whats the name of that specific tool? I like how fast

  7. that guy you hate on April 29, 2023 at 3:33 am

    Where can I get them?

  8. jeff sharp on April 29, 2023 at 3:34 am

    I hear my ammo talking in the middle of the night as well.

  9. Jason Househam on April 29, 2023 at 3:35 am

    hi John thx for getting back to me still an not contact them I have tried and no reply I have called them and email them so could you try and call them to see if they are OK all you may get one for me and I can pay you for it

  10. Frank ''Smak'' Smaknisk on April 29, 2023 at 3:35 am

    Test with a compressed or lightly compressed load to see if it will accentuate the changes..

  11. Mark Spencer on April 29, 2023 at 3:38 am

    Brown Machine llc makes thermoforming tooling, like that clamshell container. If your running that product at your business.

  12. WES on April 29, 2023 at 3:38 am

    What are you going to change or keep it all the same?

  13. MrLurcherman on April 29, 2023 at 3:42 am

    I would never of know this I seat at 2tho neck tension in my fclass 284 so hope they don’t move much

  14. Yukon 454 on April 29, 2023 at 3:43 am

    Put the results in the mtm box with all of the cartridges. Put it in your vehicle, then test the same ones, 500 miles or so from now.

  15. 2whl4re on April 29, 2023 at 3:44 am

    With just half a thou neck tension, can you move the bullet just pushing on it? If so, could just handling them also make a difference? Like when you pull them up out of the clam shell by lifting the the cartridge by the bullet.

  16. Steve Cascaden on April 29, 2023 at 3:44 am

    Does he realize that the paper he is writing on is most likely .004" thick so a perceived difference of .001" or .0015" is not much at all.

  17. Dru Bradley on April 29, 2023 at 3:44 am

    That is interesting… I wonder, if you lay the box on its side, what kinda issues may result, if any? Please note, I am so far away from being able to be this demanding on my self.. but, some day, I look forward to being this picky, as I try to squeeze every bit of accuracy out of my projectiles… Kinda like how I use to squeeze every inch out of drag racing a FORD 2.3 ltr inline 4 cyl turbo engine.. LOL I gotta crawl before I can run..

  18. gorillamotors on April 29, 2023 at 3:45 am

    Try using a standard paper hole puncher and punch out some 1/4" thick pieces of sponge (like you put on top of the bullets) and put them in the bottom of each of the bullet holes.

  19. Rusty Voice in Wilderness on April 29, 2023 at 3:45 am

    What is that length measuring device called, manufactured, sold?

  20. Center Plate on April 29, 2023 at 3:45 am

    that was a great test, makes me wonder how my hunting ammo or ammo thrown into my eberly stock is effected. does a bullet binder solve this or make the ammo more exposed/susceptible? if you use a . 282 mandrel will that make the ammo more robust? id love to see what happens when you start shooting side by side groups.

  21. Dirt-Mert on April 29, 2023 at 3:47 am

    Good God if they are that fragile wouldn’t you think he wouldn’t hit the bullets with his hand. Wonder how much they changed with that?

  22. J G on April 29, 2023 at 3:48 am

    If you do this test again I would be curious to see what the results would be if you laid the clam pack sideways vs up and down. BTW I love your videos ❤️❤️❤️

  23. JAT on April 29, 2023 at 3:48 am

    John did you check the concentricity of the bullets that were laying horizontal? Just asking if they might have moved also. Thanks!

  24. NT_Wicked_Bunch on April 29, 2023 at 3:50 am

    I let an ol green mtm box of 223 plinker ammo ride around in a tool box in the bed of my truck for a year, out of the 45 in the box 11 of the bullet dropped completely down into case. Wasn’t really a test, they just got buried after a range trip and forgot about. So travel variance is a thing. Might not matter to some but most reloaders are perfectionists and there is not point in wasting time/components if one doesn’t do their part to minimize changes. Thanks for the video and info man.

  25. EitriBrokkr on April 29, 2023 at 3:52 am

    And now you know why real ammo is crimped

  26. H Sharma on April 29, 2023 at 3:54 am

    Bro you have to be an engineer in your professional career…as an engineer myself, nobody else can be this meticulous and detail oriented in their craft to the level of being OCD. Even your testing methodology screams engineer or scientist, but I guess that’s what’s required in F class.

    Not saying that in the intent to dox or anything haha

  27. James Klink on April 29, 2023 at 3:54 am

    Good test , Thank you # !!!JP

  28. Randall Bernard on April 29, 2023 at 3:54 am

    Let me just say yes they will move !! But not if you factroy crimped them.

  29. UponGiantsShoulders on April 29, 2023 at 3:55 am

    In my loading of a gas gun with 4 thou neck tension I get 1 thou movement long when chambering. At first I was startled, but I guess its expected without a crimp.

  30. David Medrano on April 29, 2023 at 3:56 am

    I’m going to check my rounds later this week. I just drove 1700 miles!

  31. M M on April 29, 2023 at 3:57 am

    Interesting test John. Thanks. I have a few questions. Are your measurements 100% repeatable? I’m pretty sure I watched you measure the same bullet from the box twice and get a measurement 0.001" apart(First at 8:21 measured at .754 and then at 11:13 measured .755). Also a 3 foot drop is going to shock load them way more than almost any drive and would skew results. Seems to me that driving them on a padded surface(such as a back seat or carpeted trunk) vs shipping them is going to be vastly different and should be separate tests.

  32. Jacob Terherst on April 29, 2023 at 3:59 am

    The test was flawed, you mentioned UPS but failed to steal the ammo!

  33. Ramsin Pourian on April 29, 2023 at 3:59 am

    Slight crimp should resolve this problem. Also, temperature fluctuations causes expansion / contraction of bullet therefore it causes them to sink slightly. Not worth loosing sleep over it.

  34. Wyatt Larsen on April 29, 2023 at 4:00 am

    Thanks John. Informative. Do you have a video on the bullet seater? Curious about the internal components of the die you use, adjusting it, etc.

  35. Ammolytics on April 29, 2023 at 4:06 am

    Interesting! Thanks for sharing this!

  36. rdsii64 on April 29, 2023 at 4:06 am

    Where can I get the tool you’re using to take the measurements?

  37. Richard Briscoe on April 29, 2023 at 4:07 am

    What’s the measuring instrument? It’s certainly easier and quicker to use than the adapters on a caliper.

  38. Robin Epps on April 29, 2023 at 4:07 am

    Where can I buy these clam cases! Do they make the for bigger calibers, like my 33xc?

  39. Hot Chihuahua on April 29, 2023 at 4:08 am

    How do you sleep at night knowing your bullets are not what they use to be ! 😳
    I did watch the entire Video out of interest , now I won’t be able to sleep . 😂

  40. John L on April 29, 2023 at 4:10 am

    This looks like an elaborate search for an excuse.

  41. Brandon D. on April 29, 2023 at 4:16 am

    Thanks for the video, what foam are you using for mtm case and where did you get it?

  42. BigDmike on April 29, 2023 at 4:16 am

    Nice test. I plink and hunt. Think God I don’t shoot competitively. Would be fun tho.
    The ole lee factory crimp die will have to solve this for me. I am moving away from Lee sizing and seating dies. I can tell the difference between Lee and RCBS and even better seems to be Redding.

  43. Cannon Roberts on April 29, 2023 at 4:16 am

    So does this mean you seat long and then reseat to correct length before the match?

  44. justin petrovich on April 29, 2023 at 4:17 am

    Where can I order some of those clam shells? Thank you

  45. peteralexben on April 29, 2023 at 4:17 am

    with a compressed powder load they can grow also over time with a light neck tension

  46. andy347495 on April 29, 2023 at 4:18 am

    Good to know. I wonder how much it helps prevent movement with say .003 neck tension vs the .0005 you are using. Maybe that would be a good test.

  47. DOUGLAS L. ASH on April 29, 2023 at 4:18 am

    thank you John! maybe you might want to try a heavier taper crimp? lol

  48. lane nebraska on April 29, 2023 at 4:23 am

    Us regular reloaders, just use the Lee factory Crimp Die… stops all bullet settling/moving 😉
    Just saying 🙂

  49. Angel Corral on April 29, 2023 at 4:24 am

    Is that comparator from Accuracy One Shooting Supplies? I don’t see it on your page.

  50. Big E on April 29, 2023 at 4:27 am

    Now we see why people final seat at the match!!!
