for teh last two rifles....if it aint broke don't fix it!
we occasinally hunt with a guy who hunts with an old belgium made (never heard of the brand) .270 with an old weaver 6x. thing is at least 50 years old but one of the sweetest shooting rifles I've ever seen
x2, some of my dad's guns are well older than I am (not that it takes much) and the majority of them are tack drivers. My favorite is an old browning lever action 257rbts. Used to be his favorite gun to hunt with, but he hasn't used it much since winchester quit producing the 100gr silvertips for it.
