I’ve never had any issues in 2 years when using Pit Boss Pellets. All pellets have the potential to swelling from moisture, humidity and water due to improper storage. I prefer using Lumberjack Pellets because many are 100% wood type flavors and not blends... but for the price of $8.80 a bag, the Pit Boss pellets are still a good deal and safe to use IMO.
