My AR-10 does everything I need it to do. It's the largest caliber in rifle I have if you put the Mosin Nagant in the same category.
I no longer go out in the field, shoot hogs from the front porch of a friends place in east Texas while having a cool refreshment and an occasional cigar. Feeder is 68 yards away.
Still sit out in sunflower fields first weekend of dove season with my 12 gauge. It's a weekend party I really enjoy. About 30 of us get together for that one, an annual tradition. I'm the oldest one there but still compete well.
Hogs and dove are about all I go for now-a-days but who knows what's next.
I'm too old for all that shoulder thumping of the larger caliber weapons.
