Ammo storage in cabinet lock top

[Dombo63]

What about bolting the safe in place upside down?

Depends on the type of lock. I asked Brattonsound about bolting their safes to the floor on the their backs but apparently the vault-type locks need gravity to work properly.

Potentially 1200 rounds of FB ammo. I think you may struggle to secure them all. For a little extra, buy a large ammo safe from Argos/B&Q etc and have that fitted at the same time as your gun safe. That way, as the bug bites hard and you add more firearms, you will have plenty capacity for ammo.

This is interesting. If the cabinet is bolted to the floor on its back, the ammo locker is like a box.

Internal dimensions of the locker are 203 x 407 x 346 mm so a volume of approx 28.5 million cubic millimetres.
A .303 round has a base of 14mm diameter and is 75mm long, so if we ignore its tapering pointyness and consider it a cylinder, it has a volume of pi x r squared x length:
3.142 x 7 x 7 x 75 = 11,500 cubic millimetres

28.5 million divided by 11,500 gives roughly 2,500.

So 600 each of 308 and 303 should fit nicely with plenty of room for some little .22LR rounds and the bolts for the rifles chucked on top clapclap

If you base it on MTM type 50 round boxes which are how people often store them. The R50 box is 145x75x100 high so you are not going to fit 1200 rounds in unless some are stored loose or are in smaller milsurp type cardboard boxes.

Are MTMs the plastic boxes with individual compartments for the rounds? I was thinking just store the rounds loose in the locker and take what I need to the range or buy it there. I doubt I'd ever have that much in possession.
Thanks everyone for advice.

Yes the MTM's are the plactic boxes as you describe. Storing them loose is not an ideal method for any type of loaded round, better to keep them in boxes if possible. Having said that I would have thought the vast majority of ammunition you are going to buy will be boxed in 20 or 50 round cardboard boxes and they do stack quite nicely and take up less space than the MTM's so you should be OK.

I do also agree regarding the number held, we can hold several thousand here but seldom get close to capacity.
