This dimension on the original MKI pellets are 6.68 - 6.70 mm while the MKII pellets measure 6.58 - 6.60 mm. The appearance of the skirt or back of the pellet can vary.

My Air venturi Avenger loves them, as does my Armada. You can't go wrong with these pellets.

It's not so important what I like. What is important is what the .25 Air Venturi Avenger bullpup likes, and mine seems to like the JSBs.
Things I would have changed:Nothing
What others should know:If you're looking for a pellet that hits with power, this is the way to go.

Has anyone tried these in a Hatsan Flashpup?
Does anyone know if this fits in the Marauder magazine?
Yes
Can anyone tell me how these shoot out of a Mod 125 Sniper, I really want to try these in this powerful springer.
The Hatsan springers usually shoot JSBs pretty well, I'd think they'll group solidly in your gun. But you never know until you try

Very well made pellet. They group well and the weight of the pellets range in half a grain for the most part which is always good for consistent groups. My Gauntlet 2 25 caliber and my Modified Air Venturi Avenger 25 caliber love them.
