My brothers gun is a traditions pursuit and mine is a cva accura and I do have the black horn plug. His gun has only fired 2 times on primer only. We kicked up some does this afternoon. He takes a shot but primer only goes off. So he takes a shot with my gun and it goes off like normal. After looking for blood its a complete miss. Temp was negative 2. So we reload my cva and head to our evening spot. I let him use my gun and I sit in stand with bow. Temp is negative 6. He has some deer get in range and takes the shot. Says it fizzles and burns powder. But bullet just go a few feet. So what caused this ?
