I don't have any experience in long rang shooting, but I have "plenty" in the "lay aside my hobby and put my family first", ha. In your stated reasons, its the 300WM. The "wildcat" will want more of your "time & money". Trust me, I'm 65 and been married to the same girl for 45yrs, raised twin girls, still Pastor the same church for the past 27yrs. I am a rifle looney from birth! ha Yet there are times you have to lay it aside ( or at least cut back) Life is too short as it is. You are a good man to even "consider it" though, so don't be hard on yourself, ha.
