Feeding a 10 gauge is not inexpensive
Some useful links of US companies that may have 10 gauge reloading supplies:

http://www.grafs.com Graf's uses flat rate shipping for most items so while the unit rate might be higher, you MAY save on shipping.
https://www.ballisticproducts.com/ I've used both Graf's and BPI and been happy with both. Never had a need to buy from Track of the Wolf, but they have been around a long time.
