Any .25 caliber bullet suggestion for a stock Airforce Condor SS

I just got the gun new two weeks ago. Finally got to shoot it this week upstate NY. The gun is great and shoots the JSB 33.95 gr pellets at about 935 fps on the power wheel number 5.5 for about 65 ft lbs I believe. The 25 grain JSB were well over 1000 fps and had to lower the power. But both were very accurate. But I would like to try a solid bullet that works in this gun for fox, raccoon, and maybe a coyote this winter. If anyone has this gun or has a suggestion I would love to hear it. Actually any suggestion about the gun would be great. Thanks in advance.
