308 gets the call for me these days. I've had at least one 06' for the past 40 years but rarely used it as I preferred a 270win. A few years ago I got a 308. Gave my 270 to a grandson and now I use a 308 for whitetails, hogs, and an elk (in 2016). I did use the 06 for my elk this year but will probably use a 308 next year. Either cartridge works for me, but I'm liking the 308 for now.
