HuntingNet.com Forums - Whats the difference????????????????????

I would suggest that you buy the newest reloading manual that you can find. That will answer about all you would ever want to know about all cartridges. Also a new book Cartridges of the world. I should say an updated version of this book.

In the caliber you are talking about, there is not really enough difference to set one much above the other. Lets face it, a game animal would never know the difference. The most common is the 300 Win Mag. You will find ammo for them about anywhere. Its suitable for all North American Game. The 300 WSM is getting pretty widely used and ammo can be had a WalMart and all real gun stores and the shops like Cabelas and online at outfits such as Midway. The Remington Version 300 USM is not finding wide acceptance and In my mind will soon be obsolete. The 300 UM is pretty popular and is a bit less powerful than the 30-378 from Weatherby. The 300 Weatherby Mag is close to the same as the 300 UM.Out to 250 yards, the 30-06 will do the same jobs as the 300 Mags. It depends on what range you want to shoot. If I had to have a Magnum right now, My choice would be the 300 WSM. Its going to stay around and become more and more popular.
