I would rather go with a 7mm STW over a 300 win mag. Shoots flatter and outperforms .300 win mag past 250 yards in terms of ballistics.

...I have been working on longer range 30-06 bullets and have found a good load with 240gr Sierra hpbts out to 1300 meters and using IMR 4065...
The .300 goes on out to about 500-ish as effectively as the .30-06 does inside 300.
.243 Win. (that's what I use)
