On 12/31 I posted a problem w/my cylinder sticking after 25 - 30 rounds down range. A friend at my LGS looked it over and found the cylinder was rubbing the forcing cone. After a few rounds things got hot and shut the gun down. He took some very fine sand paper and worked on the forcing cone and now all is well. He ran 160 +/- rounds through w/o a problem and I'll be picking up the gun later this week. Thanks to all that weighed in & a special thanks to my friend Mike who's on this Forum.
