got my new pellet grill... it has a high temp of 500 deg.f I used some 100% cherry smoke ring pellets, but the highest temp I could get is 440 deg. I switched out the pellets with pitboss competion blend hickory, maple, cherry and now it cranks up to 500 deg easy. the smoke ring pellets have a smaller dia , but I think its the wood type. next I will try 100%hickory to see if it will over shoot 500 f. then I will know for sure its the wood type. anyone else notice this? peace, randy.
