And those are clinkers....they look EXACTLY like like the ones i had in my Astoria one time.
Interesting, I never had them in my Astoria. Do you remember what pellets you were using? If they were Hardwood or Softwood? Any pics?
Were they as big as the ones I show.
I did see your one pic in this post but clinkers are not as big or the same shape.
