This round is ideal for shooters using bolt-actions or single shot rifles (but is perfectly safe in semi-automatics although it might not completely cycle the action). This subsonic ammunition is a perfect choice for shooting through your favorite rimfire suppressor. This quality ammunition will meet all your shooting needs. This ammunition is new production and non-corrosive.
