Loading for my 450/400 I’m having trouble finding boxes to hold the rounds when I go to the range. I usually use the various sized MTM boxes for other calibers. But it doesn’t look like the make one that fits the 450/400 other than bullet down. I’ll do that if I have to but prefer a bullet up configuration.

I like the MTM because the plastic they use readily accepts labels I can write the load data on and they peel off without too much residue.

What is everyone using to organize and transport you bigger bore shells?
 
I use Plano part PL123020 and MTM Case Guard J-20 for the 450/400 3”

I have used plastic boxes from three manufacturers for my .450/400 NE ammunition. All three are bullet-down only.
MTM H50-XL-24 (holds 50 rds)​
Berry's Model 412 (holds 50 rds)​
Scheel's Magnum/Ultra Magnum #212 (holds 20 rds)​
If I might make a suggestion however... When I first started reloading for this cartridge, my loading block would not fit the Jeffery's larger rim. I solved this by making my own loading blocks. Perhaps you could do something similar by cutting a piece of scrap lumber as an insert to fit the MTM box and then boring the appropriate-sized holes. I used a 5/8" Forstner bit when making mine.

Incidentally (and you may already know this) the only difference between the different models of H50- series boxes is the removable insert.

Thank you. I already made my own loading block.

I didn’t realize the H50 boxes have a removable insert. The onesie for my .375 and smaller rounds the interior is not removable. I’ll pick a couple up and play around with making something.
 
Berry’s makes a flip up lid box that has cartridge slots a little larger than the MTM box and it will hold 500 Jeffery diameter cartridges unlike the MTM(I am away and can’t post a photo/model number of it). Berry’s also has a 10 round box that is designated for 50 BMG and 505 Gibbs. BERRY’s has a booth at SCI.

Yes, the insert comes out just as slick as a whistle. But one would need to deal with the molded-in guides for the insert.

Another idea for your consideration: Since your goal seems to be bullet-up storage, why not use a bullet-down box, but store it turned upside-down? The MTM wouldn't work due to the handle. The Barry's might work but I would be concerned about the effect of 50 cartridges' weight against the flip-top lid. However the Scheels has a flat lid and the latch appears sufficiently stout to remain closed against the weight of its 20-round capacity. Just food for thought.

Addressing the issue of an ammo box lid sliding off, popping the lid up, or coming unlatched … an appropriate length of blue painters tape can be your best friend.
 
Some 12ga shot shell boxes work for large cartridge, rim down- both hinge top and slip top. Some of the universal shot shell boxes have spacers in compartment bottoms so may not work for holding rim down, large calibers.

See you are from Denmark - see quite a few Danes where I stalk in Scotland - great hunters.
The Harkilia stuff works well in Africa - I have a bit for use here in UK.
I am again looking for 600 Nitro dies preferably RCBS 1 inch. The set I purchased previously are 1 1/2 inch and do not fit my die. Another member has graciously taken them off my hands. If anyone happens to have a set of 600 Nitro Dies that will fit my Rockchucker Supreme RCBS press, please shoot me a message and thanks in advance for any assistance you may have to offer!
I have not posted any items for sale on this forum and will not every put anything for sale. My account was hacked and I've worked with the admin to get things shut down.
