The 25-35 Win is a fine old cartridge, as is the 25TC/U, and I've had both, although in handgun lengths. My first choice in this class though was the two 257JDJ's I owned, both handgun lengths. Dies are no problem and not expensive from SSK, 225 Win brass not hard to get like it once was (I still have 1000 new) and is very strong, and like the 25 TC/U they do not need to be fireformed to start hunting with them. Solves Alan's rimmed brass choice, but that never mattered to me due to the way I headspaced rimless in my Contenders. I'd go with a 20" barrel if it were me.
