Yes the JSB Exact RS are the same as the Falcon Accuracy plus pellets both made in the same factory in the Czech Republic.
I have tins of both and they are good pellets with a slightly flatter trajectory due to there light weight
only 7.33 Gn and very consistent when theres no wind
but they really take the wind even if its only a slight breeze.
On a calm day they are brilliant
But in my opinion they are just a little too light. (but then I'm in windy Scotland lol )
Try them though they may work for you?
