$4 per round?!? If you already have brass, it should be less than $1 a round!! If you need brass,, make that .25 cents a round considering its 2.5 a lapua case and from everything I have read, they should easily go 10+ loadings. Even at a super conservative 5 reloads a case that will be a total cost of 1.50 a shot. It's honestly not as expensive as I thought. I'm just getting into reloading, and the savings on these huge rounds is enormous. I paid the same dollar a round for 308 factory ammo!
Honestly, I think the cheapest round is HSM rounds. Its like 2.5 a round. If your just starting you can get those, and it is said that the brass is norma brass. So you can save your shells and reload those!
