Hobbs Batting! Lots of it!
I was planning to order some charity batting from Hobbs and talked to someone there and they suggested I place an order of at least 180 pounds and they would send it by truck for $150. That price comes out to .833 cents per pound, which makes a 96" roll ship for less than $14. Of course, I'm not going to use all of this. Some of it was ordered for other longarmers in the area.
