I chose an 06. I like 30 cal especially on elk sized game. 06 ammo is priced the same as 243, 308, 270 etc but it is a more powerful round.

I can tolerate the recoil even at the bench yet it delivers enough energy to anchor an elk out to 500 yards with the right bullet, which is probably farther as I have any business shooting any way.

Not to mention ammo is readily available etc.
