I've noticed that CB caps are available in 'lr' packages, ie they are powered by a primer only like a cb cap, but are physically the same size as a .22lr round to enable cycling them in magazine fed guns.
They don't have enough 'oomph' to cycle a semiauto, and must be cycled by hand.
I had an idea for a fun, easily reversible modification.
Would it be possible to replace the recoil spring in a semiauto rifle with a weaker version, thus allowing these rounds to cycle the action?
The problems that I can see are:
1. The mainspring and friction between components being too much for the pipsqueak round to overcome.
2. A suitably weak recoil spring would not be powerful enough to strip a round from the magazine and close the bolt for the next shot.
3. The bolt may open before the pressure drops to a safe level.
One would naturally have to be very careful to esure every shot left the barrel before firing the next round, too.
Silly pipe dream, or the funnest little plinker ever?
