I'm getting myself back on track after a LTR with a girl who was likely BPD. One of the suggestions I keep seeing is to find some SMV raising hobbies, however I'm a single dad so I haven't had many hobbies lately. I'm really into firearms but with ammo/gun prices so high, it's hard to justify going to the range.

What are some SMV-raising hobbies that could also increase the likelihood of finding a decent girl? I've been considering rock climbing, biking, or getting involved at church (sense of community + volunteer work + more traditional views). Does anyone have any experience or insight? I appreciate you guys
