Just recently purchased a Rem 700 SPS DM in 30-06. I have no need for it, but it was a good deal I couldnt pass up.

Now I have this rifle and I dont know what to do with it.

I'll definately rebarrel it and throw on a nicer stock.

Here is a quick list of chamberings I already own.

204 Ruger
22-250
243 Win
240wby
257wby x2
6.5x47 lapua
6.5 Creedmoor
260 Rem
7-08
7mm Rum
280ai
30-06 x2
300wsm
338 lapua
338 win
338 edge
35 Whelen
375 Ruger

6mm-06 and 6.5-06 are both pretty cool but kind of have them covered already.
25-06ai would be neat but the 257wy covers that.

Any suggestions for cartridges?
