ergh… hate to say this but matchstick bombs sound like they would be far too low-powered to do anything useful with. Pipe-bombs, likewise are way too underpowered right now. they should certainly have enough punch to kill a zombie outright, but as they are right now if they don’t fail they can’t even OHKO a zed.
Molotovs certainly aren’t underpowered-- but that’s mostly because they spread fire easily-- and fire hurts.
However someone just had a suggestion in the bunker which I just have to add: RC car bombs.
Let’s stick in remote control car toys in some shops and stuff.
Primary skill: Electronics 2
Secondary: Traps 2
Tools: None (Maybe a soldering iron, I dunno.)
Ingredients:
RC Car
Duct tape
Nails (25)
Pipe Bomb x2/4 OR C4 x1 OR Grenades x2 OR Any other explosive you care to mention except molotovs.
If we go the electronics route, throw some a little bit of wire in, 5 should be enough. Maybe even add in the option to stick a noisemaker or radio on it for added crazy bomber style points.
As for gunpowder, gunstores should stock big tins of it. However, making a simple grenade from black powder is pretty easy. Tin, powder, fuze.

You’d need one hell of a lot of flour for an FAE and the dispersal mechanism itself would be even harder to make.
Not that you would be restricted to flour, though. That could be a use for those coal pallets you find in the shacks outside mines.
Scrape coal pallet into coal dust.
