In the case of the HW this would involve nearly running it dry I had 2 and if either so much as sniffed an oily rag the first few shots looked like they were old SAA colt's....
If power really is the be all for you then for I'd plump for CO2 power in the shape of the extremely customisable 22xx model, I've still got my custom one long after the HW's have gone.
my crosman 2240shoots at 4.5ftlb over the club chrono.
it went with such a bang, at first we were worried it might be over 6ftlb.
it groups quite well too. for a fifty quid gun.
i am the master of suspense;but?
I have an HW45 in .22, bought in the first couple of months that they were imported, it's had many thousands of pellets through it and has never needed a repair.
My 45 is running at 5.5 ft/lbs and is not hard to cock, is not harsh or unpleasant to shoot, and is very accurate but requires consistent technique for consistent results - speculation to the contrary on these points by those who don't own one is just that
Back on topic I've just finished a service on a Rohm Twinmaster Top which is running at 5.2 ft/lbs whilst still having a useable double action trigger

I've only had my 2240 a couple of weeks but it's easily powerful enough to reset targets, and accurate enough (even with the bog standard iron sights) to be fun. I'm not sure they can be beaten for what they cost, and then you can mod them so much that it gives you something to do when you can't shoot.
