These are excellently made BBs that biodegrade. They have a perfectly smooth outer surface and no noticeable inconsistencies. They have never jammed my Madbull V.2 Tightbore, and they give me great accuracy and consistency with my shots. Their heavier weight makes them less prone to being influenced by the wind, and they have more "punching" power that allows them to travel through foliage without too much interference. I should add that G&G includes a silica gel packet inside of the bag that absorbs moisture.
