I currently own a .338 and have shot a .325WSM and believe me when I share with you that you will definitely know when the gun has gone off. The recoil, while very manageable, is something to consider for plain shooting enjoyment. Another caliber to consider besides the 300 wsm
is the ol' reliable .300 win mag. The win mag has many options in factory ammo and if you are a handloader, you have far more options for bullet selection when compared to the .338 and particularly the .325.
