I have a half dozen of them, use them in my 795 and Papoose.
The mags all feed 100% reliable in both of my guns, however the last shot bolt hold open almost never activates. They do have the tab that should catch it, but I'm guessing the spring is just a bit too weak for the follower to get up in time to catch the bolt, because if I cycle the gun manually after the last shot, the bolt will catch.
Still use them extensively. 25 rounders are pretty much mandatory where I shoot gophers (target rich environment).
