I have owned both a Tikka Light and Kimber Montana in 300 WSM. I was 64 years old and a small man at 5'7' when I bought the Tikka. Shot hundreds of rounds through it and then traded for the Kimber Montana just because annd shot hundreds more. These were my Newfoundland Moose hunters. I shot a wide variety of brands and weights. Both rifles shot most everything well. Under 2"at 200 yards. I settled on the 180 TSX which shot diagonally through a moose. In the back left ham, broke bone, exited about middle right shoulder. I had a 3 leg homemade portable bench I shot off. Both rifles had a Limb Saver pad. I hot rodded them to the max and loved shooting them. Bullet weight made a difference in noted recoil.
Tested about every powder available in the RL 17 burn rate. In these 2 rifles Hodgdon 4350 was the ticket. In BOTH. It did the best for me any temperature and about any weight of any bullet. Shot it in 90+ degree and -0 degree days. Point of impact varied little at 200 yards. With that powder I had the best velocity consistency and accuracy. I settled on the 180 TSX for the moose. Shot 2 whitetail with that load. DEADLY!
What would I do differently?
150TTSX! Faster, flatter, flies through Moose with aplomb. These 81 year old shoulders may also appreciate that decision. Given the opportunity I'd hunt any North American species with it.
Light weight 300 WSM, Hodgdon 4350, Winchester mag primers, 150 TTSX, mmm, mmm, good!
