Hey mate, sounds like your dad is right into it. The hobby does have a habit of taking over I guess. Lol. It's rewarding to go through the process, make the rounds and then fire them accurately. The process all comes together at the end and it's such a good feeling. I'm sure your dad would agree.
Do you shoot yourself and if so do you hand load. If you don't shoot why didn't you follow in your dad's footsteps?
