Here’s the curve for JSB 18.13. Mean energy for 1st 30 shots (27.9 ft/lbs) is same as for 15.89 grain pellets; it should be, but nice to confirm. Lower velocity for heavier pellet also makes sense. But while curve for 15.89 grain pellet is nearly flat, for 18.13 it has typical shape for an unregulated rifle. 

I’d really like to know from the experts why this is.
