I think the lack of ability to scale up production is the key problem the west has. Russia has state owned military industry that never dismantled the infrastructure it inherited from USSR. Once the war started, Russia was able to quickly put mothballed factories back into operation.
On the other hand, the private sector in the west sees doing such things as a huge waste that gets in the way of profit. Not only that, but they're also leery investing into building out the necessary infrastructure since they realize the war will end eventually and then there's going to be little use for it. In fact, shortages play to their advantage as they're able to jack up the prices for whatever they do produce.
