In games of Fortnite, streamers such as Ninja often get the maximum amount of medium ammunition possible to carry, and light bullets as well. Does anybody know the maximum amount of shells you can carry?
Small ammo cap - 999
Medium ammo cap - 999
Heavy ammo cap - 999
Shells cap - 999
Rockets - 12
Hope this helps! It may be hard to get max shells and heavy ammo types, but it has been done in modes like close encounters and sniper shootout.
Whilst the limit shown on the bar where your weapons are stops increasing at 999 the various amounts of ammo you can get increases beyond that. I have personally seen ammo increase easily past 999 into the 1200's. I have never noticed the hard limit myself but the wiki gives the following numbers although it isn't clear if these are for Save the World or Battle Royale though as I noted before I have noticed an increase above 999.
Light Bullets: 6000
Ammo for weapons that use low caliber bullets. Typically used in weapons with a high rate of fire. You can carry up to 6000 light bullets.
Medium Bullets: 4000
Ammo for weapons using mid-range caliber bullets, tyically with balanced firepower and rate of fire. You can carry up to 4000 medium bullets.
Heavy Bullets: 1000
Ammo for weapons that use high caliber bullets, typically for slow and powerful weapons. You can carry up to 1000 heavy bullets.
Shells 'n' Slugs: 1200
Ammo for weapons that use all types of shells, such as buckshot or slugs. You can carry up to 1200 shells 'n' slugs.
No information is given in the wiki but my experience and that of others here tells us it is 12.
The max amount of medium and light ammo is 999, heavy ammo is about 70, rockets are about 12, and shotgun shells are around 80 excluding any already loaded.
