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.

Just curious as to what you are cooking at 500 F?

Different pellet types (species and manufacturer) can have slightly different BTUs. On grills where you are pushing the top end of their rated output, it can make a difference. The higher end grills typically don't have a problem with this. I can hit 700F on my Memphis with any pellet.

Species Million BTU’s per Cord Pounds Per Cord Dry
When reading that chart it's important to factor in the weight per cord. Just looking at BTU's is misleading because BTU vary mostly due to wood density. Cords are measured by volume, pellets by weight. Once wood is pulverized and pressed into pellets, most of the density differences are eliminated and the difference in BTU is due to other factors like oils and resins. That's why softwoods are low in BTU by the cord, but are have some of the highest pellet outputs.

I actually used the data in that chart to create one that calculates the BTU per lb - I think I've posted it here but I'll see if I can find it.

The image post you linked to no longer shows the image. At least it doesn't on my computer.
