I was just checking Cabelas and they have Long Beard XR 6s in 3 and 3.5". :z-guntootsmiley: I don't know how many boxes or how long it will last. Also, I'm not sure if it applies to ammo but $99 order gets free shipping.
Update, free shipping does apply to ammo.
Price is $18.99 3", and $22.99 for 3.5"
