.22 LR target practice and plinking
.308 for all 3 catagories you can load it down with super hot lil 75 grn pills for everything from cotontails to your yotes , load 110 or 168 grn slugs for deer and other game in same weight class or load it up with 190s and drop black bear and Elk
this is assuming at least minimal hunting skill so ya aren't forced to depend on glass and 800 yard shots to drop an Elk as some hunters think its illegal to take deer/elk within anything closer that 500 yards........ I go for the 20-25 yards myself (been a bow hunter my whole life) and at 25 yards a .308 is more than enough for even the largest Elk or griz both of which I've taken with a bow already so figure anyone who can avoid getting drunk the night before the season opens and who isn't confined to a wheel chair or dragging around 300lbs of body fat should be able to do likewise, thats where the .22 comes into play..... spend alot of time stalking rabbits, with their hearing its great practice and once ya can stalk up on a Jack without him alerting..... elk become easy
