Love that No.1. I just bought the same gun in 257 Roberts a month or so ago. I have a No.1 B in 243 also.
Nathanael... Try a Remington 760 or 7600 pump. I found a .243 7600 pump at an estate sale a couple of years ago and I LOVE it!The .243 is pretty popular here in Texas, or at least it was until magnumitis took over.
I'd like to try a .243, but being left-handed it's hard to find a lot of options.
