So I finally took my new PS90 to the range. I had never fired it and have only changed the barrel shroud with the Huntertown Arms shroud so I can use my suppressors while waiting for my SBR stamp. The shroud switch was a breeze, no problems and I'm pretty good with stuff like this so I'm confident in the switch over. At the range I had two mags loaded with SS197SR. Made it through 35ish rounds with no suppressor and all was well, shots were consistent at 50 yards and grouping well after zeroing my Z-Point. Decided to try out my Spectre II, have used it a lot on my various 22s and it's working great. The very first shot fired but after that nothing would, and a look at the chambered rounds showed no primer hits. Tore it apart at home and finally found that the one round that fired suppressed, the neck and shoulder of the brass had separated from the body of the brass (which had ejected).

Now I'm pretty familiar with shooting suppressed, had the suppressor screwed on right with a spacer needed for this shroud, so I'm confused. Any ideas why the neck and shoulder would separate? Thanks for any help.

Glad to hear that Huntertown Arms shroud is working out for you.

I actually just went to the range today and had the same issue shooting my PS90 SBR suppressed. First time I had seen it happen so been doing some research and I came across your thread. Glad to see it worked out for you. Guess I'll be going to scrub the hell out of my chamber and give it another go.

I'm guessing the added fouling from shooting suppressed plus maybe the coating that is on the PS90 brass just got the case shoulder stuck. Not sure about yours but the part that was left in the chamber came right out after I got home and punched to bore with a cleaning brush.
