Hey, I'll go one more....7.62 NATO 'battle rifles' are fun to shoot. A short barrel FAL? Is like you're Thor wielding Mjolnir...it's damn fun and I'm all for that as an excuse to own one.
I tend to think of high volume hog hunting as being one of the few places where we regularly see conditions that favor 'battle' rifles over other platforms here at home. And even there, a 6.5G, 6.8SPC, or .300BLK will tend to do what is needed.
I agree that 7.62 is becoming more of a "niche" round. Particularly, now that we have 6.5G and 6.5CM, we're seeing the efficacy of the 6.5mm bullet profile at longer ranges from the Creedmoor, and at shorter ranges in the Grendel - there isn't much that 7.62 does better...
