I fitted a new rubber breech washer (from Knibbs I think), I had to trim about 1mm off it to get the barrel to latch, but it was a fantastic improvement in power over the leather and brass original which had dried out and started to crumble - no amount of oil would restore it!
My power measuring is based on bean-can bashing; when I first got it, 0.22 pellets would bounce off, but after the new seal, they would punch hole in the can, sometimes though both sides.
However, my 0.22 Tempest will easily punch through both sides, and is a darn-sight easier to cock. But I still love shooting my Senior!
Too many guns, or not enough time?
