Reloading cost

Yeah you need to figure out what components you are going to use and rough powder charge. Do some simple math and whola!

Edit:
From my limited research it is similar to 300 WM. So i would assume its close or slightly more expensive then 300WM
 
I've done the exact thing, figured around $0.79 per round for decent (not the cheapest) components

$0.03 primer (Federal LRM Match)
$0.36 powder (Rl-26)
$0.40 bullet (Hornady 225gr ELD-M)

I don't count the cost of brass as I view buying brass as a separate investment. Just me though
