    N/A Muzzle energy varies with pellet weight, WHY?

    Yeah, It is sort of pressure distribution between connected vessels with variable outside forces. Does anyone know of any physics literature about it? It should not be too complicated physics (Freshman level probably). The more I go into it the more I want to buy PCP!

    #6 reply make sense, I never thought it would be so dramatic.

    N/A Muzzle energy varies with pellet weight, WHY?

    Thank you everyone. Unfortunately, all this does not explain why Gamo rifles show this energy drop, while Crossman Pumpmaster does not have even a slight drop. All these rifles operate through expansion of limited gas volume. I only can explain this effect if Gamo being the break barrel rifle...

    N/A Muzzle energy varies with pellet weight, WHY?

    Hi I am new here I posted it in general discussion, but here it seems more appropriate. I want to show my energy measurement results on 3 rifles with 16 different types of pellets (all 0.177 caliber) 1. Gamo Swarm Magnum Pro Gen3i (30 J energy according to Gamo) 2. Gamo Swarm Maxxim 10x Gen2 (20...
