If you know the muzzle velocity and your altitude I can run you one. I do have one for my son's Apex shooting 130gr of Pyro pellets that would probably be close. Here it is with altitude set to 500 feet and set up for a 5" point blank range sight in.

The extra 20gr of powder will maybe add 30 to 50 feet per second to it, not enough to make any big changes to the chart.
I hope this helps.
