I think you made a good choice. On bullets, I would not rcommend the Partitions for long range shooting. Partitions have a soft lead point that is easily deformed and a poor BC. They would be good for ranges up to 200-300 yds, but beyond that I would recommend a different type of bullet with a poly tip. For your shooting, my choices would be...
110 gr TTSX
140 gr AB
130 gr TSX
130 gr Trophy Bonded Tip
You might try all of them and pick the most accurate. The 110 TTSX has an MV of 3400 fps which will make it a very flat trajectory out to 500 yds, but it will be on the edge of it's killing potential at 500 yds.
