Well with 560 rounds per pound of powder with the 12.5 grain Load...

say primers at 3.5 cents apiece....you have more in primer than you do the powder....

and then factor in your cost of the bullet you choose...

Hornady Bulk bullets ( from various sources) and Nosler's Shooters Pro Shop are you friends....

definitely rivals the rimfire magnum costs, with better performance....

and you factor in seeing things like a box of 50 CCI 22 LRs were on the shelf and selling at Fred Meyer last night for $8 something a box....

just bought a ton of bullets from Nosler's Shooters Pro Shop... for under 10 cents a bullet.. and that was delivered to the door step...

in Klamath County Oregon, there a ton of little gophers hibernating and new ones that are in gestation right now, that they unknowingly have their name on one of the zillion bullets I have loaded and to loaded for this coming spring...that will start in February or so...
