Affordable Caps

Lastly, the over pressured cartridges move faster and when they come in contact with the hard ejector they can and often do become damaged faster that the cartridge that has only one cap..

That's an interesting point Mark, I'd always assumed that the cartridge rims were being damaged by the bolt face and extractor hitting them hard. I hadn't really thought of the consequences of the cartridge hitting the ejector hard enough to damage it too.
I've certainly seen how double capping using MG or Marushin caps produces excessive blowback which in turn cycles the bolt too quickly leading to jamming etc.
Interesting things these model guns aren't they ?!
