7mm remington mag, normal ol' 308 (7.62x51), and 338 winchester mag

Thinking of picking up a new rifle. Would like something good for reaching out a ways , just for bragging for bragging rights.

Seems 308 is lacking compared to the other 2 for energy, and on longer distance, accuracy.

338 is pricey, and somewhat rare. Although even current, is on the shelf, where 308 is out of stock.

7mm seems slightly more common that 338, slightly less expensive than 338. Seems maybe more rifles made in 7mm over 338 as well. 7mm seems a little more off the shelf ammo choices, and a little more of it on the shelves currently than 338.

Ballistically 7mm and 338 are way ahead of 308 of course. However 7mm being smaller, I get to thinking the pistol thing "45 never shrinks down to 9mm". So makes me think the 338 would be a better choice for elk. Now the flip side, 338 seems a little overkill, potentially wasteful on deer. Which gets me spinning back to maybe 308 makes the most sense, and just learn to deal with it for longer range.

So yeah, fence sitting, and keep flipping back and forth? Currently arguing with myself, and losing!
