The problem with dieseling is that the extra power is not consistent and is offset by resulting inaccuracy.
Have you notice that the first half dozen shots after oiling the barrel tend to go astray? That's dieseling.
On one of my .177 rifles, there is a marked increase in retort if it diesels. That rifle's already well over 1000 fps, so the extra power may be spitting out at supersonic speed and the extra noise is a sonic crack (speed of sound is approx. 1125 fps)

LS if you are using the standard 8 grain pellet it better not be going more than 820fps or you are into the FAC required area past 12 pounds power.
But you are correct on the dieseling thing. It is totally uncontrollable and erratic.
I would think that dispatching trapped critters would be more efficient using other methods. A good stout stick comes to mind.
Did it ever occur to any of you that the law only allows you to have these 12 pound guns because they are useless?
Well spotted MB, and you are right. Several of my pneumatic rifles are in FAC territory.
The .177s work best sub-sonic where the pellets fly truer in my experience.
