300 RUM brass is becoming easier to find. I have seen it in the for sale section here quite a bit. The 215's are still hard to get, but they will come back. In the mean time, you can get 210's, 230's or even the 200 Accubonds.
That is true. I have a scope in the safe I could piddle with on it for now just to see what it can do. Maybe put a new trigger on it and see what I can get out of it. I know what you are saying about the SPS over the BDL. This just works out because it's my buddy's and the price is half descent on it.
I think my future plans would be to use my 270 for whitetails when I go back to ND, 7RM for muley's, and the 300 RUM for elk, but we'll see how I feel about it when it comes to spending the money. My 7RM is plenty good for elk too, but a 300 RUM would be a nice addition.
