I have 2 go-to loads for my 243:
85 gr Partition pushed by IMR4064 around 3250fps
90 gr Accubond pushed by IMR4350 around 3190 fps
The Accubonds took the deer I shot this year, both 1 shot DRT's.
Both shoot to the same POI out to 200 yards. Past that, they start to separate. Both shoot nice, itty-bitty bug holes.
