I had a play out of the box and it was a bit 'boingy' so stripped and properly lubed the mechanism. Now fires with a smooth clunk and running an extreme spread of 5 FPS over a 10 shot string so very consistant and smooth in so little time.
Running at the high end of power so will need watching as things bed in completely and run in especially with the Bisley 24grain slugs.

At 30 yards it is slower moving when compared to .177 and .22 but there is a lot more of it when compared to my normal .177 bis mag and .22 accupel when it does arrive.

If nothing else it makes the target holes easier to see on paper
