Things I liked: I shoot daily. These .177 pellets shoot noticeable more accurately out of my Gammo Whisper break barrel rifle than any others I've tested. I shoot squirrels, reactive steel targets , paper and 9mm Brass Cases hanging from cord at 16 yards in my back yard. The Exact pellets are accurate and consistent for my uses. Squirrels get very few pears out of my tree.

What others should know: I shoot a lot. The Exact pellets are a little pricey but worth the money.

  • Justin from USA asked:

    I am looking to buy a DPMS A4 which is rated at 1200fps on light pellets. I shoot in my basement at 14 yards. I want to make sure im not breaking the sound barrier. Will this be Overkill and inaccurate? If so, any recommendations?

    • John from USA:

      This pellet at 10.34 grains is not a light pellet, it is considered a heavy pellet. You do not have to worry about it breaking the sound barrier when shot thru the DPMS A4. Light pellets are pellets that are 7.9 grains or less. Buy a chronograph. Woodys World.

  • Tommy from USA asked:

    What is the height/length of this pellet?

    • Tyler from USA:

      Right about 6mm or 1/4"

  • Mike from Canada asked:

    I have a Stroeger X20 .177 (+1000 fps), that I am having difficult in getting a tight grouping (tried the Gamo Rocket Ballistic Tip 9.6g and find every 4th shot to be a flyer) could you recommend a pellet for this rifle for shooting squirrels (short range no more than 20 yards), I like the JSB Match Diabolo Domed Pellet, should I go with the Domed 8.44g or the Heavy Domed 10.34g?

    • John from USA:

      You could use either one. They wont do 1000+ fps. The 8.34 grain should perform better. Are squirrels wreaking havoc or shooting them just for sport? That Stoeger is a mid power air rifle. Get a chronograph. Woodys World.
