I finally got my blued 4.25 to the range for a work out. I ran some 38 special through it without issue. When it came to 357, a few casings would not eject. I managed to push them out with a rod. Tried again and same thing. I've only shot one brand of 357 so far. It's Freedom Munition from LAX Ammo. I've read some bad reviews of it but the ammo has worked with all my S&W 686's. I brought a dozen shells home to check things further. It seems that only a few casings would hang up but others went in and out fine. I read here that cleaning might help so I gave it a good cleaning today and tried the spent brass again with the same outcome. Next trip to the range I'll try some Federal ammo. I'm a newcomer to Colt so please feel free to offer opinions. Thanks
