I agree you can not save money unless you buy in large quantity. I load all mine but I do use different cases. I use WAA or equivalent cases. This means Wads by the case. I think there are 10 bags of 250 in each one or something like that. Powder by the 8lb keg and order 2 if they will sell it. I buy my primers 10,000 at a time. Shot is a big problem. i usually get one of my kids to buy several bags at a time from someplace like Cabelas. Shipping, Hazmat, and such will eat up your savings quick.
I use a MEC with an adjustable charge bar.
