For a year now I have been trying to decide between these two calibers wanting the “best of both worlds” and have finally made the decision to have Nathan Dagley build me a Win 300. It just simply better fits the type of hunting I enjoy the most. With 200gr Accubond’s it’s a solid 800 yard elk carry rifle. One of the most deciding factors was that the Win 300 can be shot without a muzzle brake
and that eliminates the need for hearing protection while hunting. I know the RUM can be used without a brake but I’m not that tough.
If I was wanting a 30 cal 12-13 lb long range rifle not to be packed a lot the 300 RUM would be my choice.
The RUM uses considerably more powder then the 300 Win and the barrel life is shorter.
