Another vote for the 250 Partition.
According to my cheap ballistics calculator the 250 at 400 yd has 125fps higher velocity, 300fp more energy, 2" less wind drift and only 2" more drop than a 225 TSX. Not enough difference to matter in the real world. The deciding factor was I got a lot of Partitions seconds cheap. Varget or Reloder 15 work well with the 225s and H4350 or 4451 with the 250s. I suspect Big Game will work well with either but haven't tried it yet.
Cheers
