There is a Canadian gun forum where you can routinely purchase once fired Lapua brand .338 brass for $1.00 each.
It has been fired through Canadian military bolt rifles and is in great shape.
You can usually get 5 reloads out of it if you don't anneal.
This brings your brass cost to $0.20 per round.
300gr SMKs run another $0.75 each
Primers another $0.04
$0.29 for 90 gr of H1000
$1.28 per round
