" PA needs to "man" up and help you solve this issue. It's part of being a distributor. ( my opinion) They should pull another "XS" fill it, shoot it, Chrony it and see if they are getting better results. Maybe they have already done this and are not? "
PA does not show this item as in stock, pre-order only, might well be they are looking into it. It mat be a few years back they handled a top shelf springer line that had a major defect in one batch and it was dealt with well and so fast very few ever heard of the issue. I think they'll get it worked out and I think it's good someone with experience and a chrony and common se posted a throu review before a bunch got out there.
I'd wager a buck AA/PA gets it worked out asap.
