As usual, this is my humbly submitted two cents worth and you should probably get some change back.
My brother wanted to upgrade from his Remy 700 in 30-06. After much research and nashing of teeth, he bought a Kimber 84 in 325 WSM.
Now the excitement begins. What excitement you might ask? We can't get the thing to shoot. Nothing will group under 3" at a hundred. NOTHING! Accubonds, Sirocco, Barnes, Hornady and finally, my all time go to bullet, Sierra. Change powders, brass primers. Set the COAL at any and every length possible. Oh by the way did I mention that the cartridge didn't feed from the magazine? Not any configuration and that all the loads showed high pressure? ALL the loads.
After beating our heads against the wall for over two months trying to get this thing to shoot, we end up with a load using a 180 grain Barnes bullet that we finally got to shoot under two and half inches at a velocity of 2600 fps. Not what he wanted but it was time to go hunting. He did kill with that gun that year, cow elk at about 85 yards. Not much to talk about.
Got back from hunting and he boxed it back and sent it back to Kimber. On his nickel. Kimber sent it back saying there was nothing wrong with the gun but they did polish the feed ramp, chamber and "adjusted" the magazine angle.
Long story short, not the cartridges' fault, the gun only shoots a two inch group at hundred with a 180 Barnes bullet at about 2750 fps. Not much better than his "old"
30-06.
At this time he is using a stick and string so it is not much of a loss.
Once again, your mileage may vary.
