If I was to buy another bolt action new at this point it’d probably be a Winchester m70 featherweight. Nice to carry and tend to shoot well. As someone who owns rifles running the gamut between .250 savage and .375 ruger I’d say it’s hard to go wrong with a .308 or .30-06, but the 6.5 creedmoor and .270 are plenty adequate as well.
I tend to think most here over scope their rifles big time though. I like lighter weight, lower powered scopes myself. Reduces “target panic”. I don’t own anything over a 3-9x40 these days, my favorite hunting rifle (a .358 win) wears a 1.5-5x20 leupold. Can you hit a target at 50 yards with open sights? With a 4x fixed scope, that target will appear the same size at 200 yards as it would be at 50 with irons.
