That's the point: there are no Wunderwaffen.

BTW, like most of Gerald Bull-designed artillery shells (or at least: based on Bull's designs), ever since the late 1970s/early 1980s…

BTW, like most of Gerald Bull-designed artillery shells (or at least: based on Bull's designs), ever since the late 1970s/early 1980s, 155mm shells in use by NATO are all made of high-quality steel.

One of reasons is that they're creating much more overpressure on detonation, than shells made of softer materials.

Moreover, they are filled with far more effective explosives than Soviet/Russian made shells, and then they are including such 'tricks' like pre-fragmentation, or fillments with balls, 'exotic' incendiaries etc.

.....all of which is making them much more expensive, but also much more effective - especially in combination with improved precision of modern-day 155mm artillery pieces (the mass of which is based on Bull's GC-45-design).

....is one of things all the possible Soviet advisors failed to learn already while monitoring such wars like Iran-Iraq or Angola of the 1980s, not to talk about ever since.
