    Prewar air rifle powers?

    I quite fancy the old BSA underlever rifles, can anyone give me an idea of the power they have in decent order?

    I would only be interested in .177, further to the above, how much power can the be made to produce?

    In British slang an anorak is a person who has a very strong interest in niche subjects.

    Thanks Garvin, so I guess finding one capable of 11.5 fpe is going to be tricky then.

    I re-built one a while back, did nothing spectacular, new spring from Troubled Shooter polished the cylinder, spring guide and a few other bits new seal trimmed and soaked in Neatsfoot oil etc and was shocked when I put it through the chrono. After a poor start it climbed to just under 10 ft lbs. then started to go down a bit and seemed to settle at about 8.5 ft lbs. Not bad I thought....

    I asked about this a while back.
    I have a 1910 light pattern that shoots very nicely at 5.5ftlbs with a new spring and leather washer.
    The larger ones put out higher power, for example a guy at our club has a nicely shooting Club Special doing around 10.5 I believe.

    Extremely accurate rifles when set up well and shot correctly.

    Matt.
