I've had about twenty different 300 PRCs, its an outstanding cartridge especially if you want to shoot long range, as others have said for hunting it really is comparing apples to apples,
the only real differences between the 300 WM and the PRC is no belt, tighter tolerances on the reamer specs, and its throated to shoot heavy for Caliber bullets,( you can have the same done to a 300WM) most factory rifles have a faster twist barrel, if you go the 300 PRC get an 1-8 twist barrel, in the end think of the 300 PRC of a modern designed 300 WM,
If you love to target shoot and maybe want to shoot long range as well as hunt and hand load a lot, the 300 PRC starts to outshine the 300 WM for a few minor reasons.
300 win mag designed/introduced in 1963.......300 PRC designed/introduced in the fall of 2018,
If all your doing is just hunting inside of 2 or 300 yards hell go .308 Winchester as its going to do everything you need and you have more factory ammo options than any other cartridge on the planet burning half the powder.
