I did a quick and easy to test to show how bullets can move while being transported and how some methods are better than others at preventing this from happening.

Would there be a difference in bullet up or down in ammo cases.
If you compress the charge, with they grow?
Thanks! Now I have one more variable to worry about 🤣
The clam would have done better, even, probably, if it was flat, the way you would likely pack then, instead of vertical?
AFAIK you shoot .284 Win. Is that correct? And which Brass do you use? Am getting a Barrel in that Caliber. Thanks!
Whats the name of that specific tool? I like how fast
Where can I get them?
I hear my ammo talking in the middle of the night as well.
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
Test with a compressed or lightly compressed load to see if it will accentuate the changes..
Brown Machine llc makes thermoforming tooling, like that clamshell container. If your running that product at your business.
What are you going to change or keep it all the same?
I would never of know this I seat at 2tho neck tension in my fclass 284 so hope they don’t move much
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.
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.
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.
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..
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.
What is that length measuring device called, manufactured, sold?
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.
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?
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 ❤️❤️❤️
John did you check the concentricity of the bullets that were laying horizontal? Just asking if they might have moved also. Thanks!
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.
And now you know why real ammo is crimped
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
Good test , Thank you # !!!JP
Let me just say yes they will move !! But not if you factroy crimped them.
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.
I’m going to check my rounds later this week. I just drove 1700 miles!
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.
The test was flawed, you mentioned UPS but failed to steal the ammo!
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.
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.
Interesting! Thanks for sharing this!
Where can I get the tool you’re using to take the measurements?
What’s the measuring instrument? It’s certainly easier and quicker to use than the adapters on a caliper.
Where can I buy these clam cases! Do they make the for bigger calibers, like my 33xc?
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 . 😂
This looks like an elaborate search for an excuse.
Thanks for the video, what foam are you using for mtm case and where did you get it?
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.
So does this mean you seat long and then reseat to correct length before the match?
Where can I order some of those clam shells? Thank you
with a compressed powder load they can grow also over time with a light neck tension
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.
thank you John! maybe you might want to try a heavier taper crimp? lol
Us regular reloaders, just use the Lee factory Crimp Die… stops all bullet settling/moving 😉
Just saying 🙂
Is that comparator from Accuracy One Shooting Supplies? I don’t see it on your page.
Now we see why people final seat at the match!!!
