You might consider a dedicated 300 RUM for the 230 Berger. I did one a year or two ago that is doing incredible things at long range and it's nipping at the 300 grain Lapua in energy. 230 grain bullets at 3200fps. Brass is seasonal but if you are patient it can be had.
Not to derail my own thread, but a 300 RUM is in consideration as well. Did you throat that one specifically for the Bergers? How's the round count? Think it'll make it to 1000?
