You can teach an old dog new tricks, though. I used to shoot .30 cals, including .300 Win Mag, .30-06, and .308. After getting into reloading and learning a lot more about ballistics, I decided I didn't need the .30s. The first to go was the .300 Mag, then the .30-06s, and finally the .308s. I will admit to some sense of loss when I parted with my Model 7 in .308 that was my go-to hunting rifle for a couple of decades. But I replaced it with an almost identical rifle in 7mm-08 and you know what? I don't miss the .308 any more!
Here's the original .308. H.S. Precision stock and Leupold 2-7X.
And the 7mm-08 that replaced it. H.S. Precision stock and Leupold 2.5-8X.
