I suppose it indeed depends on the size of bang we want, the bigger the bang, the bigger the weapon. Check out Bofors new AT4 AST (anti structure tandem) on You tube. Can be set to blast a big hole through a wall (bigger it seems than standard Metador) or for increased behind penetration effect.
Reloadables have their advantages, certainly with regards to lighter and more compact ammo. I still like the idea of diposeables though, increased flexibility without the need for dedicated operators.
