I think your doing pretty well with the springer by comparison with the PCP :-)
A lot of springer scores seem to be well off the mark in comparison to a PCP, the key with a springer is still the hold, hard rest, soft rest, front grip, rear only, it drove me nuts! And that was with FWB300s and Original 75s which are supposed to be re-coilless... Im just sticking to a TX200 now, sure its got recoil, but its more consistant in a true springer kind of way, and more joy hitting a 10 when they come.
