I have had a few 280s and 280 AIs. Every one of them shot 160 gr Partitions like they were match bullets. Bonus: the 160 Partition at 28-2900, shoots flat and kills stuff very dead!
Kevan, have you tried these in your 280?

These will be my last resort in this 280 because my 280 AI seems to work well or at least better than the standard 280 with nearly all bullets tried.
If those don't work then its off with the barrel and on with something else.
