  • Arash from USA asked:

    Can the Gauntlet in. 22 handle these?

    • Mark from USA:


  • Louis from USA asked:

    Does this work with The Benjamin Trail .22?

    • Mark from USA:


  • Miranda from USA asked:

    Do these work well in the Benjamin marauder?

    • Tyler from USA:

      Yes, typically very well

  • Dennis from USA asked:

    Has anyone tried these pellets in an Umarex Octane?

    • John from USA:

      They shoot very good in my Umarex Octane and Ruger Air Magnum, no complaints. Woodys World.

    • John from USA:

      Could be the pellet design, at 18.13 grains, should be shot from a magnum air gun, like the Octane, or PCP.

    • LKJ from USA:

      I use these with great success in my Ouctane. 1" groups at 30yrds. 1/2" - 3/4 when the old hands are steady...

    • JimPysht from USA:

      I have. But because my Octane is so bad (can't be "Held") that pellet comp's (9) were meaningless. Ironically, the "Fuel" .17 and .22 are very good.

  • Rick from USA asked:

    Will these JSB Jumbo Heavy .22 Cal/18.13 Grain Pellets Work in the Latest & Largest Girandoni .22 Air Rifle. Some Jumbo Pellets Will Not?

    • John from USA:

      The same caliber as the pellet. Woodys World.

    • Tyler from USA:

      Do you know what the actual bore diameter on that gun is?

  • Ronald from USA asked:

    Is this U.S. Made

    • Dan the Man from USA:

      No, Czech.

  • fred from USA asked:

    what is ballistic coefficient of these pellets

    • David from USA:

      JSB does not publish Ballistic Coefficients for its pellets. However, Hard Air Magazine testing established a BC of 0.035 for these pellets.

    • John from USA:

      Look up: Straight Shooters Umarex Octane Velocity Tests on 34 different .177 and 27 different .22 calibers. Tested velocity at the muzzle, 10 yds, 25 yds, and 50 yds fps, ft lbs energy at each distance, and ballistic coefficiency. Pellets included PBA and lead. Get a chronograph. Woodys World.

    • Rafael from USA:

      JSB Jumbo Exact Heavy - 0.22 - 1.173grams (18.10 grains) (BC 0.027)

    • Janet from USA:

      I believe that the Ballistic Coefficent of these pellets is .0330 (GA)
