I shoot both 215 & 230 frequently to 600 yard less than 1 MOA with both. I've not shot the 1000 range much but did try some 215s for the fun of it to 1,125 at a gong they had set up. Two rounds to hit the gong and the following 3 all nailed it.
not sure it was too challenging as the gong was a 24" disk.
If i recall my ballistic solver called for 9.75 MOA and I ended up right at 9 MOA with the 3 hits.
