How are you 3 gun guys carrying your spare rounds for shotgun and your rifle. Currently I am using an M-14 mag pouch for my M1A on my belt and am using my SASS shotgun slide also on my belt along with my 1911 holster.

I don't have a speedloader for my Winchester Defender shotgun at this point but can see the value in using one.

I carry my rifle mags in tactical tailor pouches. They are light and flat when empty.
I just changed to a Mark Otto load 2 rig for shotgun.
