I snagged this Custom Leathercraft backpack tool bag on an Amazon Lightening Deal to use as a range bag. I loaded it up with 650 rounds of ammo, 1 full size handgun, 6 high capacity magazines, 2 sets of low profile ear protection, extra sets of disposable ear protection, 4 sets of eye protection, small lube/tool range kit, flashlight, range log and various rags. I could easily fit a second handgun with additional mags, no problem. The bag is certainly rugged enough to handle the weight load of more ammo but I doubt I'd still be about to sling it on my back.It's now had a couple of trips to the range and I am extremely pleased. The material is thick and durable, the zippers are tough and the stitching is heavyweight. There is an ample amount of interior pockets so everything can be organized in its own spot. An added bonus is the row of pockets in each compartment that are the perfect size to hold individual magazines. I have noticed I could use a couple of wider pockets though so a bit of customizing by cutting the stitching in between some smaller ones should fix that. There is an elastic strap sewn into the interior flap which is great for keeping lightweight items like glasses in place at the top of the bag so they don't get crushed.The back and straps are padded which make it comfortable to carry. The bottom has a semi-rigid form (approx. 9"x11") sewn into it with rubber grips on each corner which keeps it from sitting directly on the floor. The bag sits upright nicely without flopping over and all compartment zippers can be open fully to the bottom which makes accessing everything inside very convenient. The two heavy duty loop carrying handles on the top of the bag make it easy to move the pack around when it's not slung on the back.For a quick trip to the indoor range, this is a great bag and I have no doubt it will withstand many, many years of range use. My husband had a good chuckle when it arrived and I told him of its intended use. Now that he has seen how well it functions and the practicality of my choice, he has requested one of his own.Bonus - this is a fairly anonymous looking bag and therefore does not advertise the presence of expensive firearms. Nondescript is a good thing at times.
