300wm is relevant at LR. 7mm not as much but could be. They both get the velocity up but they're not as popular as the 6.5s like 6.5-284 or 6.5 cm or 260ai or 6.5x47. In 7mm there's the 284 win which is very popular. Wikipedia shows the 284 next to a 308 and a 7mm and it's instructive.
In general for long range you don't want everything you can have, you want just what you need.
Think lower recoil. Shorter action length . Higher BC bullets. Regular cartridge over belted mag. And case shoulder angle steep over shallow.
You want to move the high BC bullets faster while burning the powder efficiently. Although you might think that high velocity is everything, turns out how you get there is important.
Lots of folks like 338 Lapua. It's got a lot of testerosterone fore 1000 but over 1500 it's pretty much the winner short of pure wildcats.
Me? I shoot a 260ai (when @Velzey doesnt have it) and I like it. My buddy shots competition and has 300wm but prefers 308 Lapua magnum. (338 necked down to 308)(handload only although a real CIP cartridge)
Starting out? 6.5 sweed. 260. 6.5cm, 6.5x47. If you really need to buck the wind, 6.5x284 ( barrel life about 1000-1200 rounds)
If you're impressing other shooters 338LM.
