BSA Standard power

[Oldandshaky]

Hi,
I have a "T" pattern .22 1936. A couple of years ago I sent it to Dave Hall to make it smoother to cock and shoot he had it for some while but when it came back it was transformed. It has an artificial piston washer and a different spring, I've never opened it up to see what else he's done but he told me it wouldn't need any lube for years.
When I first tried it out it was doing about 10.75 ft lbs, I put it away until this week when I decided to try to sort my small collection with a view to getting rid of some of them.
There was a little smoke from the first few shots, when it stopped I tested it with 14.5 Super domes it was doing 11.50 11.75 11.60 11.78 with the highest reading of 11.84 not bad for a 1936 rifle.
Then I tried some 15.43 BSA Elite's and got readings of 12.40 12.54 12.48 12 .57 with the highest reading of 12.84. I had no idea that an old rifle could reach that kind of power I will test it again later with some other brands of pellets and I'll test my other standard that has the more conventional leather washer.
What I would like to know is what power other owners of these wonderful old rifles get from theirs...
Thanks for looking Dave...
