Hamer's hot ones claim to fame is their pellet is made up of primarily red oak and they burn very hot. I would put them as one of the finest pellets on the east coast.
There are two different plants that make Hamers- Elkins and Mt. Hope. The Elkins pellets burn much better than the Mt Hope ones in my stove. They produced about 1/4 the clinkers for me. They are a lighter in color as well. It is almost like the Elkins and Mt. Hope pellets are two different brands, It will typically say on the bag where they are produced.
Depending on the stove you use the clinker issue may not effect you. I burned some of these in a Harman and it was not issue, because the clinker cake just got pushed over the edge of the burn pot every so often.
One big advantage to hamer is there is very little in the way of long pellets. The pellets lengths tend to be less than 1/2", which is a major advantage for stoves sensitive to long pellets.
I would highly recommend Hamer, but I would try to get ones from the Elkins mill.
Please add you experience with this pellet in the comments section.
