jwp, I doubt you ever will see any difference but all of us are affected on some level by nostalgia and when it is backed up by long experience it is hard to change. My favorite load for the 30-06 and .300 mags over the past 35 years has included the 200 gr Partition
No doubt, the 220 works for you and others and always has. For me the flatter trajectory of the TTSX and their excellent terminal performance make them for me an all round choice for any and all game.
In the 80’ I loaded the 200 grain partition.
