I have three of your four, I don't have the 6.5 because it's way too much case capacity for a 6.5 and suspect that it's a major barrel burner. I have had several 300s through the years,but the recoil is much worse than the 257,270,and 7mm.
I have killed the most game with the 270,it's very flat shooting and carries plenty of bullet weight for just about anything on this continent.
The 257 is a wonderful,light kicking,flat shooting laser beam for deer and antelope,and with the right bullets is plenty for elk.
The 7mm is the most versatile of the group,and it's has plenty of heavy bullet options in premium controlled expansion bullets as well as really high BC long range bullets.
If I am hunting deer on the edge of water,and I want him dead right there,257 weatherby is in a league of it's own with 100 grain bullets.
For deer and hogs,I use a 270 weatherby with 140 ballistic tips or accubonds.
Out west,I have mostly used the 7mm with high BC bullets in really open country. KIlled with it at 400 and 500 yards without issue.
