Ammo for the Russians (or probably the Ukrainians) is not the limiting factor. Barrels wearing out is what will silence the big guns and before silencing them will limit their effectiveness. It is much easier to ramp ammo production than to replace or repair barrels. The west with exponentially more industrial capacity than Russia will easily win the war of production, if the war continues for long and I doubt it will. The Russian people well noted for their endurance in defensive wars are much less willing to sacrifice in aggressive ones.
he covers all that along wi using tanks as indirect fire and THOSE barrels are harder to replace... it’s worth watching
