In 1954 I got a Winchester 94 in 30-30 for Christmas from my dad. I still have it, and it's got more elk and mule deer kills than I can remember. It's a perfect gun for dark timber still hunting. I never found a need to replace it for CF hunting.
I did get into muzzleloaders, and enjoy that too.
I'm not the type to get bored with something I really like. It's actually a test for me. If i'm getting bored I know I haven't found what I really like yet. That's why I tried all forms of hunting when I was young. They all bored me, except still hunting, and i'm still not bored after all these years. I think it's safe to say at this point that I won't be.
