I have decided to go with another magnum caliber and want to go with the .30 cal. I have narrowed it down to the 300 Win Mag and the 300 WSM. I would like some pros and cons on both of these and a direct comparison if anyone can provide that. The information that I read about the 300 WSM suggests that many are not getting the numbers published in the reloading manuals in terms of velocity. I am looking for the cartridge that will take game at the longest distance. I also read that some people have a hang up with the belted cartridge. I have never understood this. I have spent plenty of time behind a 7mm RM and never saw were the belt made any difference in terms of accuracy say compared to a 30-06. If I can get the velocity out of the 300 WSM, and since I can use the same bullets with both cartridges, what is the advantage of the 300 Win Mag, especially since I would be using less powder with the 300 WSM.
