I gave up in the end, cut the stripper back to od 18mm and fitted an oversize tube just
Like the ftp , hopefully now sorted ,
cheers for all your feedback guys

Vinny, there's a slo-mo video on Youtube somewhere of how a PCP barrel vibrates on release of shot. May be worth finding as it's a lot more than I believed and could be the root of your problem. Short of that I'd speak to Jon Harris or John Gray as they've done loads of work on barrel harmonics. Good luck.
