Ooooh, nice...do you think there'd be a market for a trolley where they were all pointing forwards, and you could pull on a bit of string so that all of the rifles or shotguns fired at the same time?

Or has someone else already thought of that? I really wanted to be a millionaire by the time I was forty, and so now I only have two years to come up with the Next Great Idea...

Like the idea,want one although i would need one for each hand!

Another vote for forward pointing! As it stands there's going to be something just a bit uncomfortable about where those muzzles are pointing when pushing the trolley...

I don't know about a market, but it was created and demonstrated during the US Civil War, loading 40 or 50 rifled musket barrels onto a cart, with all the percussion locks triggered at once. It was one of the competing designs being offered to the Army about the time the Gatling gun was first being used in combat during that war.

One of many attempts to create a rapid or mass fire weapon. Of course, the Gatling design had all the advantages: metallic cartridges, magazine feed for continuous reloads, et cetera.

Someone recreated one of those multibarrel carts for a History Channel show. When all those barrels full of black powder fire at once, the entire gun carriage disappears into an enormous cloud of white gunsmoke! Good for one volley, then the crew had to start the muzzle reload. Took forever, with their backs to the incoming enemy fire. No thanks.

Or you can go the traditional route...

...which includes a box for the ammo.

And you can even go upscale.

What we really need are country clubs we can shoot on, and make proper use of those cart's mobility.

Every golf course I see strikes me as a waste of a perfectly good shooting range. Take a golf course, and replace the greens with targets and grass covered berms.
