Rifle marksmanship is still relevant to some just as golf is relevant to some. That list can go and on, fishing, photography, cooking, quilting, etc. Pick your pastimes and enjoy life. I also love to take "outdoors" pictures, including animal photos and have played golf a lot in the past...not so much at this age, but my daughter married a golf course owner so I "have to" do it once in a while.
Personally I don't give a hoot what anyone thinks of my pastimes. I love to shoot both rifles and pistols and intend to keep doing it as long as I can pick up either and press the trigger...relevant for today or not. We rarely shoot shotguns for fun here; only about twice a year to tune-up for fall, but love to hunt grouse and woodcock.
I love shooting rifles and handguns, but don't do it much during the winter, even though my buddy and I go to the Club's indoor range a few times. I'm very lucky to live next to my son and his 200 acre forest/blueberry field property. I shoot off the porch sometimes and keep varmints off bird feeders, etc.
We can shoot up to 450 yards across blueberry fields, but my benchrest is set up in a wooded hedgerow where I normally shoot 100 and 200 yards, but have gotten deer, coyotes, crows and a bobcat in that field (not from the bench).
Still, homes are encroaching on the safety perimeter and I have to be careful to shoot in safer directions, even when hunting, because there are houses within a half-mile in a few directions, including my house. I'm especially conscious about ricochets, due to the many boulders, seen or unseen.
(I should be sorry for the long post, but...)
