Im going to be 59 in couple months.I carry more rifle, that is lighter,bipod, 2x the optics,3x the range finder.Of when I was younger. Im probably slower on a fast timber shot, but better at LR. I packed a 340 wby for over 35 years,shot a few bulls and first as my son too with 243. Been shooting bulls across canyons for 30+. For my type of hunting a 338 rules. I did 14 hard mountain miles on one hunt last fall muley hunting.Still want it just as bad as I did when I was 20. But cant handle as much tough terrain.Last 12 years been running 338 NM, we get several animals a year in the 5-600 range. Have several friends running same, ones rifle has taken close to 40 elk, many pushing 1000 yrd. Shot a few bulls in ID and MT with my 325 wsm,son too in the 500 y range 200 NAB.I packed that lil 325 for years because so light,but always felt under gunned for the area I ran.
