RE: Really need help!..300wby, win mag, or 7mm rem mag?
I would go with the .300 Wby mag.. I have one and really like it. I use factory loads as I don't hand load. The .300 Wby is closer to the .300 RUM than the .300 Win in ballistics. The .300 RUM will also have more recoil over the .300 Wby. mag just like the 300 Wby. has more than the .300 Win mag. The .300 RUM has less offerings in both loads and rifles than the other two.
