IIRC, the 7mm WSM is 1.702" length to the shoulder, vs 1.664 on the 270, 300 & 325 WSM iterations.
only time I've had problems with the WSM's is when I played Kimber Roulette with a wood stocked Classic, and when I tried to resize for a 6.5-300 WSM (6.5 Leopard) out 7WSM brass.
Being a low volume shooter, I've been able to lay in a lifetime supply for each.
I do believe the 325 WSM is my fav!
ya!
