Many Star Wars fans claim no (including on this site, I see the claim often backed by no citation), as does one journal entry for Star Wars Rebels: Rebel Journal by Ezra Bridger (at least according to Wookiepedia's article http://starwars.wikia.com/wiki/Slug#cite_note-EBJ-2; any quotes from the actual book would arguing one way or the other be greatly appreciated). However, in Aftermath, Jas Emari kills many stormtroopers with her slugthrower.
Here are some quotes from the book (this happens several times in Life Debt):
Page 332 (Jas is armed with a slugthrower):
Already, they’re waving her toward the Halo. A pair of forest troopers comes up a long spiraling ramp—one is already on her, so she cracks him hard enough with the butt of her gun that his helmet spins. The other gets a point-blank shot to the chest plate. It splits in half and he goes down, his armor shattered and smoldering as he twitches.
This is made more explicit on page 364:
Jas takes down troopers left and right with her slugthrower. Jom is altogether more brutal—he and the Wookie get right in there, scraping bodily with their foes, flinging white-armored incompetents left and right often into one another.
