I enjoyed my 7 WSM. It was quite accurate with Reloder 19. I gave it to my son in law when he moved to Texas. I did not seek to buy another as I already had a substantial collection of 280's by then.
My custom 280 AI is my favorite of the bunch.
I own several good sheep guns:
Sako 85 Finlight 300 WSM 7 lbs
Borden 300 WSM 7 lbs
Borden 280 Ackley 7 lbs
Wby 280 UL 7 lbs
The 280's run 140 Accubonds at 3000 fps
The WSM's run 150/165 Accubonds at 3050+ fps
