Brocock/BRK Folding stock adapter and other accesories for Atomic XR in .22

So I'm 15 fps less, should I tweak HS?
JTS 16.08g pellet: Most fpe and accuracy in my Brocock/Brk Atomic XR. I get another 1 or so fpe and 20 fps out of it than H&N Baracuda 15 which is 15.89g They seem a little cleaner than the H&N Baracuda 15 and usually with no skirt damage/deformation as I sometimes see with H&N Baracuda 15.
