but soon will. We are talking about conservation of energy here. The cocked spring with the piston in front of it represents a FIXED amount of energy. The laws of physics dictate that that you cannot create any more energy in the system than this.
I read on a CO2 forum an interesting contradiction, that CO2 pellets deliver higher velocity than lighter pellets. This again appears to defy the laws of physics if on assume that the CO2 delivers the same pressure behind the pellet regardless of pellet weight. However, there where chrony listings to support that this was true. With numberous pellet brands and guns. So what gives -
I too had thought that the possible solution was that a heavier pellet resists motion longer, there for developes more pressure behind it, and then gets a harder push (ignoring diameter issues). This is my prevailing theory to support the reported CO2 numbers, but one cannot consider this with out considering the energy losses. I suspect there could be some differences between calibers and pellet weights.
And back to springers, if a heavier (or logically larger diameter) pellet provides more resistance to the spring, then this is simply more resistance against the release of the spring. Lowering a spring slower does not harm it. Just letting it go might not be good. Futher, letting it go against any pellet is better than no pellet, otherwise the spring/piston could slam into the front of the chamber.
I see some math in my future, unless someone sorts this out for me soon...There's alot of variables in this equation to sort out. The laws of physics always win in the end, so there's something missing in the explanations offered so far.....
Let's keep this going til its understood by all!
