I think the only time that the Knight Sabers have fought boomers, in the series, who were not part of someone's plot (Mason, Largo, Quincy, Miriam, Largo again) was in Scoop Chase, which is when Lisa took a picture of nene in her suit. And even then, it could be argued that they were a part of another Genom's plot.
Frankly, all those boomers weren't so much rampaging as much as purposefully destructive and dangerous. There's very little evidence, in canon, that "berserk" boomers "broke free" from their "shackles" and decided to get the hell out of dodge.
and it's been shown that when boomers do go on a "rampage," they kill pretty indescriminately all the while growling and what-not instead of sitting down somewhere and singing "We shall overcome."
