I finally found a source for pellets other than the big box stores and am currently working my way through 25 bags of Uncle Jed's soft wood pellets. Cost is $5 per bag. First impressions are positive, much less and finer ash and a good couple degrees more heat in the rooms the stoves are in at the same settings as hardwood/Marth pellets. I previously tried their Western Elite Ponderosa Pine pellets and Northern Elite hardwood mix pellets as well. The Western Elite worked OK in the Bosca, but no improvement in the Winrich. They are also kind of sticky feeling and don't seem to flow in the hopper very well. The Northern Elite pellets worked well in both the stoves, better than Marth, but with comparable ash, as expected.
I think the Jed's are worth the extra money and plan to load up over the summer.
