Definitely small. Looks like a single shot rifle in there, some .22, and given that, I am wondering if one or more black rifle is not a .22 or airsoft. Piddling amount of mags and ammo. I have more than that for just one of my least used pistols. That looks more like an Uncle Jim Bob out in the country type of collection, not a terrorist, and certainly not a serious gun enthusiast let alone a collector (who would have at least 20 variations on a single model of a gun). The ammo is barely enough for one family afternoon of range fun. I have around 20 handguns, 30 long guns, couple of hundred mags, and a few tens of thousand rounds of ammo and consider mine a small-medium “collection.” If you have ever seen a serious gun nut or real collector then you are talking at least medium to large.
