Thanks all for the suggestions. I am using Winchester Super Target and Federal Field and Tgt loads; #8 shot. During match there is usually 30-40 minutes between shooting so the gun cools off. Its possible the gun lube is wearing off during match so I will try adding lube in-between stages. It is not practical to drop a cleaning rod down barrel as I am actively engaged in the stage match and that would be a lot of time and safety issue on the range. I just have to muscle the forearm to rear to get the shell to eject and suffer extra time.During a match after 50-60 rounds I am not able to eject the spent round as the forearm will not retract. After much effort I can get the round ejected and then the gun runs OK. Any suggestions?
That almost always indicates user error (weakness in operating the slide or short stroking the slide). I base that finding on my experience as a LE firearms instructor for about 16 years and having witnessed it happen time & time again usually with the same shooters over the years; although, it occasionally can happen to anyone. I would check the gun by taking it and operating it myself and if I could do it without a problem - then give it back to the shooter who then operated it without a problem after instruction not to short stroke and to use enough force to operate the slide - I chalked it up to user error. It can happen to anyone including myself even though the shotgun was one of my favorite weapons with which I practiced profusely and the damage to my right shoulder can attest to how much I used the 870.After much effort I can get the round ejected and then the gun runs OK.

Wait what!?!?! Of my two competition shotguns for 3-gun (Benelli M2 for Tac Ops and a Stoeger P3000 pump for Heavy), neither one of them really needs any attention for many many hundreds of rounds or more. No joke or embellishment at all here but my M2 has close to 25k rounds on it and has only been cleaned at most maybe 6-8 times ever. My P3000 is much newer and has only seen a few seasons of competition so the round count is much lower but I actually haven't taken it apart and cleaned it since putting it into service. It has been used in 2 or 3 dozen competitions since then, many of them being 150-200 rounds each. If you can't get more than 30-40 rounds out of a gun then there are some other problems going on there.Can you give it a quick clean and lube mid match?
When I go over 30-40 shells in a match, I usually go to my second shotgun.
Thanks for help and advice from others. I think taking it to a gunsmith is next.Thanks all for the suggestions. I am using Winchester Super Target and Federal Field and Tgt loads; #8 shot.

BTW: I am reaching out to this forum after this reply from Mossberg Customer service. I quote
"Thank you for your email. Based on your serial number the shotgun you have is 22 years old. Unfortunately, this is a very odd thing due to the fact it does it briefly and then works fine again. Especially with it being cleaned regularly."
What are the bars?Try tightening the bars to the pump action. I had a Winchester that had ejection issues & that solved the problem.
Here's a video of full break down on a 590 Check if the bars are worn or bent where they make contact with the bolt. Or take it to a gunsmith to have them check it out.OK, and how is that done. They don't appear to be something fixed by shooter.
