  Mzl
  Mzl-videos Remington offers the UML in two different models.
  Mzl-supplies There is the standard model and the LSS
  Glossary The LSS sports iron sights and has a laminate stock.
    The UML sports a Bell and Carlson synthetic stock
   
    Both models come with a 26 inch stainless barrel. 
    It is fluted and uses a 1:26 twist. 
    They are .50 caliber and both weight in around 8.5 pounds.
    The two models are outfitted with the Remington X-Mark Pro externally adjustable trigger. It is adjustable from 5 to 2.5 pounds.
   
    Loads
    Remington claims that you can get 2400 f/s or more from the muzzle using 200 grains of Triple 7 powder.  This is pushing the Remington branded Barnes 250 gr Spit-Fire sabot bullet.
    With 200 grains I averaged closer to 2,500 FPS
    with the 150 loads it was around 2,100.
   
    primed cartridge cases
    Remington sells these in a bag of 24.
    If you have reloading equipment, you can easily pop out the spent primers and seat new ones.  https://www.youtube.com/watch?v=8LrnSe8E1dE use Remington large rifle magnum primers
    The cases are nice and heavy and should hold up to for a long time.   also Winchester large rifle magnum primers.
    And they’re meant to be reused—there isn’t an extractor to rip them free and toss them into the woods.  elongated version of the .45 ACP
   
    In the comments
    The action screws were very loose. After cranking them down to 50lbs from where they were shipped (about 10lbs) this gun shot a 1 MOA 3 shot group at 200 yds.
