Good thread. I would have chosen the 300 win mag with a 215 too.
One thing that seems off is the predicted velocity of the 338 win mag with a 300 gr bullet. 2400 fps seems slow. Is this with a 24" barrel?
I get 2500 fps with a long throated 338 RCM and the 300 gr Berger using a 30" barrel and RL-17. I would think a 338 win mag would beat this especially if it had a 26" or longer barrel.
Anyone have actual numbers?
I don't have any actual numbers. According to QL, though, 2600 or so from a 26" barrel can be had in an accuracy node with the right powder. VERY compressed loads with RL-33 could conceivably yield 2690 in an accuracy node, but I don't know if one could really get enough powder in the case for that to be possible. Perhaps possible if throated for the 300's?
Some experiments with HBN or moly coating bullets might be useful with such a combo, too.
