Interesting article on Air rifles...perhaps applicable to airsoft?

The article discusses how altering piston weight and cylinder volumes can make an air rifle more efficient. Curiously, the cylinder volume is decreased, and the piston is lightened.

A Perfect Formula? Airgun Design Breakthrough - Airgun Magazine

After years of R&D, one airgun technician may have just made the biggest discovery ever in terms of spring-powered airgun design. Simon Everett meets him to find out more… There are many Weihrauch aficionados who’ll tell you the earlier HW77s – those with a 25mm diameter piston – are better than...

Very interesting indeed!

I feel that a longer and thinner cylinder will definitely give more power and so will a larger exit hole.

Can confirm, this does work. You can drill out a vsr10 cylinder head to get more energy. You can also weaken an airsoft gun by making the opening smaller.

Yeah, this has been known for a while by most.
What this post proves(already proved) is that piston weighting is sometimes advantageous, and sometimes disadvantageous, which hopefully people will realize.

What isn't comparable is airgun pellet expands with pressure and has quite a bit of friction during the entire travel inside the barrel.
And the HW97 long barrel (competition model) is weaker than the HW97K (hunting model short barrel).
