As everyone know, Varget is not gonna be available for a fair old while.
When I reload that was my number 2 choice as I need something bulky.
From a bit of googling I've found that 50BMG is the same powder but even bulkier so that may be an option. Also that Reloader 15 may work well.
I'm getting quickload to point me in the right direction so I can have a play but anyone one got any suggestions in the meantime?
