Initially I had some issues running JHP but after shooting a bit more ball tried again and found it would run 115, 124, and 147 JHP's (Gold Dots, HST's, Ranger T, you name it). Being a K, it might be more ammo sensitive though.
I agree the K guns might be more sensitive. Mine is the longer barrel and I run a can and it runs everything.
