It is a fair question. The striker spring is used to bias the handle in the forward position. If you pull the handle back and let go of it, it springs forward. So no slop.
I'll try and provide more info soon, like tomorrow, but I'm still busy preparing for shot. Nevertheless, I have attached a picture below of what you can do to a case after it has been hammered, with and actual hammer, into a chamber that it wasn't designed for. This was done by first hammering a swollen 6.5 CM case into a 6x47 chamber and then screwing the barrel into the Archimedes action until the case head contacted the bolt face. Pulling really hard on the bolt handle resulted in a broken rim. I then rotated the barrel by 180 degrees and pushed the bolt forward to take another bite. I pulled really hard again and, voila, another piece of rim breaks off.
The wonderful thing about this concept is that the force you exert on the bolt handle is reacted by your shoulder. You can use a good bolt handle to pull the rifle into your shoulder really really hard and, on the other end, this force can only be reacted by the stuck case, which will either pop out of the chamber or fail structurally, i.e. the rim breaks off. The limit is now the case and not you.
The rotary cam extraction of the now "conventional" actions works only if the case isn't stuck in the chamber too badly. Beyond that and a hammer of some sort is required.
In my opinion, the Archimedes completes the bolt action, at least conceptually. If it's not a game changer in the bolt action world, then nothing is.
