Have any of you tried pulling your choke tubes after shooting the new longbeards? I shot about 2 boxes and when I went to remove my choke today and I had a hell of a time getting it out. It certainly didn't go in that hard. After pulling it I see a distinctive "ring" inside just in front of the threads. I measured my outside dia. on the HS Strut at .822 above the threads. I measured 3 other chokes and the OSD above the threads @ .817 +/- .001
Anyone ever seen this? the gun and choke are not new and I've never had a problem till now.
