Re: .300win, wthby or ultra?
I started Elk hunting with a Remington 30-06 and the moved to a Weatherby .300 Wthby. Recently I have acquired two rifles in the .300 Win Mag caliber. Over the years this is some of the things I've learned. (I should mention I have no experience with the newer .300 RUM)
1. The .300 WinMag and .300 Whby are belted cases, the
.300 RUM is not.
2. The .300 Whby is more powerful than the .300 WM;
however, on paper the .300 RUM is more powerful than
the .300 Whby. In reality I don't think it is. Reminton
is a bit timid about their factory loadings and tend to
under load the cases. Weatherby is not timid. You would
have to handload the .300 RUM to get it to be more
powerful and it can be done.
3. Any .300 Whby loading will only take a .300 Whby casing
and the brass is hard to find.
4. The same holds true for .300 Whby factory loaded
ammunition. It is expensive and hard to find.
5. The .300 Win Mag stuff is also expensive but it is not hard
to find, it's everywhere. There are several brass
manufacturers. There are many bullet manufacturers.
It's popular.
6. I cannot imagine the .300 Remington Ultra Magnum ever
being as popular as the .300 Winchester Magnum.
Therefore,
My opinion is to go with the .300 Winchester Magnum.
