I'm assuming the latter as the core of this board is paper target focused; I was just doing a "wouldn't it be nice if...?" I don't want to take the project off at a tangent.savantguarde wrote:So is this to be a silhouette gun or for paper punching? I just love ssp's so simple. The fwb 103 is pretty much the pinnacle of a muscle power pistol. The lpm 1 is no slouch either. I would love to know some better tech specs on them such as what the actuall cc they compress is.
If I'm honest though the power is secondary. In NEFTA pistol FT we shoot to 25 yards but the concern is not trajectory it is just oomph to knock over the larger silhouettes (which also tend to be the longer range ones).
I too would be interested in those specs. In theory the narrower the pump cylinder the higher the pressure that can be achieved with the same force (pressure = force / area). However a narrower cylinder means smaller swept volume unless you have a long stroke. So you need a long, narrow cylinder coupled with a long lever for its mechanical advantage. To make the most of the accelerative energy in the compressed air you need a suitably long barrel, but this in turn needs plenty of swept volume to feed it. It's probably no coincidence that the more powerful SSPs resemble each other in overall form: FWB 103, Izzy 46M, Walther LPM-1.
