I have a Marlin XT-22 that I bought about a year+ ago.. Just shot it for the first time today.. The casings (5 total) have bulges and two were split! The chamber's crap. Checked the customer service page - and since it's a 'pre-Ruger' rifle Marlin and/or Ruger won't touch any warranty.. I.e., if it needs a new barrel it's on my dime..
Nice. Thanks, Marlin (and Remington)...
