I agree the 30/30 is a great gun,I hunted with mine for a good many years. I carry a 270 with me now,mainly because my children have been usingthe 30/30for hunting,As they came of age that's what they cut their teeth on.
My son carries a 270 now as well mainly because his grandfather left it to him.
Itwasa great gun for my Daughter's starting out with it wouldn't knock them on their Butt's like some of the big cannon's some people carry.
I had put alot of venison in the freezer with my Marlin 30/30 though.
Probley when my youngest Daughter leave's the house and the Grandkid's are old enough to Hunt I will let them use the 30/30.
But you are right the 30/30 is and will alway's be a great gun.
