You won't go wrong with the 2.5-8, it is one of my favorite scopes. Some mounts make it difficult to put one on a long action other than that you will be golden. I have shot beyond 800yds with a 2.5-8 and it did great, plus you'll have plenty of eye relief and field of view.
Look forward to seeing your pics once you have it set up and hearing how you like it.
