Iíve had a nice walnut Prosport since the first batch made.
I havenít shot it too much as Most of my time is taken up with Field target.
A few years ago I shot it in the cold and noticed a power drop, so I stripped it, cleaned out all the AA lube and replaced with fine locksmiths graphite powder as the only lube in the piston chamber.
Since then the power has remained consistently good whatever the temperature and shot to shot is low singles over the chrono. Iíve owned a few air rifles in my time but the Prosport really is up there as one of the classic greats.
