marauder upgrade

Hey everyone,went out the other day in 103 degree temps and did some Chrono work with my Marauder .22, so these numbers may be a little higher than normal temps. Not sure how that works. Anyways,shot multiple pellets and one Griffin slug near the peak of the shot curve. Seems to be between 2700 and 2000 psi. These were done at the peak around 2600 fps.

 17.6 Norma = 874.6
  18.13 jsb = 854.9
  21.14 H&N = 814.3
  25.43 Jsb jumbo = 733.7
  14.3 Jsb dome = 976.2
   19gr Griffin HBHP = 814.4
 Seemed like good numbers. Just thought I would share.
