SSR 100 x Blue Night Vision Fluorescent Silicon Rubber Balls Paintballs Glowing in The Dark in 43 Cal. for Training and Self - Home Defense

I bought these to use with my GBB Co2 air pistol. They are .43 caliber, when using them ,theys jam up the magazine in the pistol, i thought there may be something wrong with the gun, however, I bought the black, hard rubber ball .43 caliber ammunition from the same manufacturer and the reason for the jam became clear, the white ones are too large for the gun, even though they are supposed to be the same caliber. I could not use them for fear of damaging my gun so I had to return them. They don't glow that much either.
