Have to admit; living in Wyoming there is a lot of hunting. Also a lot of terrain. And while I have many different rifles and guns all together, I pretty have or can shoot just about anything I want with a 7mm Rem Mag and a 22 mag. I could see possibly changing out the 7mm rem mag for a 300 win or weatherby mag. But personally, I prefer the 7mm Rem mag.
With the 22 mag rifle I have; Ruger 10-22, I have taken plenty of rabits, squirrel, coyote, etc.... Granted, sometimes a 22 mag is a little much and a regular 22 long rifle would be better, but I'd rather have the 22 mag and not need it than not.
For the 7mm Rem Mag, I have shot factory loads of 140g to 175g. I have reloaded down to 120g and 100g. I have shot coyote, whitetail, mule deer, wild pig, elk, moose, bear.
In my opinion, there isn't 1 thing in North America that the 7mm Rem Mag can't or hasn't shot. I personally think it is the best all around. Granted, the 300 mags can probably claim the same thing. I think the 300 is too big for some things. I don't think so for the 7mm rem mag. The 7mm rem mag has been considered the most popular magnum rifle yet devised. Cartridges are manufactured not only in the USA, but in Europe, Australia, and Africa. Possibly also other places.
There is no doubt that if I didn't have the money to buy multiple guns and I could only have 1, then it would be the 7mm rem mag. There will always be debates on this. Especially for the military type crowd that thinks the 308 and 30-06 walk on water. They are great, but they just aren't as versatile as the 7mm rem mag. In north america, anything another rifle can do, the 7mm rem can also. From breakfast to sniper. Later... Mike....
