Yeah, Russia is at war, though it is limited. In WW2, for an example of total war, about 1.5 billion shells were used on the western front alone, which is nearly 700,000 per day for 6 years straight. By comparrison 40-60k shells per day is nothing. Russia is ramping up production, they report that their current rate is 2.5X what they were producing a year ago, but it's a drop in the bucket compared to if they were on a wartime economy. The US, again being at peace, is even less motivated to ramp up its production. While the exact numbers aren't currently known, in 1994 the US had 20.4 million artillery rounds stockpiled. It has sent about 2 million of the oldest ones to Ukraine (equivalent to about 6 months of Russian production), and it is also selling large numbers to Israel. The army wants to boost artillery shell production because they always do, but the fact is the US does not currently need to match Russia's production rate, as it is not using shells at nearly the same rate. It's also worth noting that many other nations are likewise producing artillery shells to send to Ukraine. The limitation on western aide to Ukraine has been political will, not insufficient materiel.
