Things I liked: Devastating expansion and penetration on all game. Tight in the bore. Most accurate pellet out of my RWS mod 34. Uniform size and shape. What I like most is the thwack! it makes when it hits game. Any hit in the vital zone will be the end of your pests or game.
Things I would have changed: Head design doesn't always allow it to seat uniformly every time.
What others should know: These are my all time favorite pellets. They have weight and huge expansion. If your looking to get rid of squirrels and chipmunks, look no further.
