I have found Remington's UMC to be somewhat lower quality (dirtier and perhaps poorer point-of-aim accuracy) than other "major brand, non-premium" ammunition (such as Federal's American Eagle or Winchester's white box). This said, I would not hesitate to use it -- for general range practice -- or to buy it -- if the price was right.
