I am trying to find the weights for the Premier 3-15, S&B 3-12, NF F1 and USO 3.2-17. One of these will be my next and I'm trying to weigh things out (no pun). I have an S&B 5-25 now that is really too much for what I want so I'll keep it for my .338. If anyone knows the weights or can point me in the right direction I'd appreciate it.
