I ran a 325WSM for Northern WI deer; still have it, but it doesn't see use that often these days. It is a great cartridge and deserved better reception than what it got. A 225-230grn high bc 8mm bullet in a LW Tikka - or similar action with enough COAL, would be fantastic for elk and moose in steep country that you have to walk a long way to access.
Such as it is, I feel like most OEM loads for the 325WSM feature bullets that are more heavily constructed than what is optimum for deer. I used both the 220 PP and 200 NAB on deer and had pass through performance with relatively little organ damage. Recovered the animals, but it was clear to see that regular cup and core bullets from a 7mm-08 or 6.5 CM are, in many cases, quicker killers for the majority of shots at WT deer.
Were I to run it for deer sized game in the future, I'd maybe try some bullets made for the 8mm Mauser and run them at similar velocities to what they're designed for.
Sadly, my 325 languishes in the safe these days. It's a victim of being a minimally popular niche cartridge for which bullet development hasn't kept pace. It's also difficult and expensive to track down ammo and reloading components for, so I tend reach for the rigs that can be shot more economically.
