I'm a fan. I have a Montana also. I haven't gotten to work up much with it, but for bullet choices I have:
160gr TTSX
175gr ACP
180gr TSX
198gr Hammer Hunter
200gr TSX
200gr Nosler Accubond & Partition
220gr Swift A-Frame
The 200gr TSX is my top choice with a B.C. of 0.421 and between 2700-2950 fps. Good to 500yds, no problem. Cautiously optimistic about the Hammer Hunters...
p.s. For equivalent pressure of a moderate load, the 325 with at 200gr TTSX will be carrying about 200ftlbs more energy than the 300 WSM with a 200gr TTSX.
From your handle I think you have a Whelen. How does felt recoil compare?
