Buy the biggest gun/caliber you can shoot accurately and comfortably. If thats a 25.06, so be it. I've hunted elk for 27 years (much less than others here) and have seen elk killed with smaller calibers than the 25.06. A friend of mines wife gets the job done with a 7.08 and has for years. I like the 30's but I can shoot them just fine. Good luck !
