I was talking about artillery and now you want to talk about rockets, which is something the Russians do not have an advantage manufacturing. HIMARS can hit a dinner table 40 miles away, the Russians have nothing equivalent:
The US-made system has struck Russia’s advance and is the weapon of choice on NATO’s eastern flank.

so they need to fire more Uragan rockets at the same target.
Now we've sent the small diameter bomb which can reach out 100 miles and is easy to converts existing stockpiles to.
And because of sanctions, Russia has to find middle-men to get them the semiconductors, transformers, connectors, casings, transistors, insulators and other components made by companies in the U.S., Germany, the Netherlands, the U.K., Taiwan and Japan.
The Royal United Services Institute found that "450 microelectronics components in the Russian systems, and 81 of the components had export control numbers. They also found Japanese capacitors, British oscillators and Dutch pressure sensors in the Russian weapons. Furthermore, Iranian weapons and most likely North Korean and Chinese weapons are also full of Western electronics."

For instance, "Russia’s Kh-101 cruise missiles, some of which targeted the Ukrainian capital Kyiv, were found to contain 31 foreign components."

A circuit board on an Iskander missile looks something like this with 5 foreign chips:

So, Russia has been tearing apart washing machines, dishwashers, refridgerators and microwaves in massive numbers leaving mounds of junk to get at chips:
Wide-ranging sanctions call for desperate measures and dirty dishes.

The US has a chip shortage too but it's not that bad. If you want to talk about where Russia has the manufacturing edge and why it's with the artillery munitions and the machinery/tooling they've kept for it since the Soviet days preparing for wars on their borders in Europe or Asia.
