You can't wear it out
My dad bought a 336 in .30-30 about the same time you did. It was my favorite gun of his when I was younger and I used it for practice and for every deer season in North Carolina, South Carolina, Georgia and Tennessee for the better part of a decade.
I know without a doubt that it has had at least 4000 rounds through it. I always used 170 grain softpoints and whatever brand was cheapest at the time. That gun has never once let me down.
I'd say around the 3000 round mark or so, I noticed things didn't seem right. The gun felt a little loose.
I took it to a local gunsmith I knew in Oxford, Georgia and he said all it needed was to be taken apart, cleaned good and have all the screws tightened. When I picked it up from him, it was as good as new. He charged me $20 and said other than cleaning and tightening he had to replace one screw.
That gun is still in my dad's safe and I still take it to the range about 3 or 4 times a year and put a hundred rounds or so through it every time I go. It still shoots great and is still nice and tight.
You can't beat one of these guns for a good all around target and medium game hunting rifle.
I'm told the new Marlins are like the newer Winchester lever guns. They are okay but they take a lot more maintenance and are not near as good a gun. The accuracy is still there but they have to be "tuned up" and taken completely apart and cleaned every 500 rounds or so.
I prefer the pre 1964 Winchester .30-30 myself. I have a couple of 1894 models and a Saddle Ring carbine. They have held up very well also. I have put about 1500 rounds through each with no problems and I bought all of them used. No telling how many rounds have been through them. You know how most folks are when they sell you a gun. "Yep, it's almost new. I bet I ain't put 100 rounds through her. Blah, Blah, Blah."
When you know darn well that a gun made before 1964 and bought in the mid 1990s has more than likely had at least 500 to 1000 rounds through it if not more.
I have one new 1894 model Winchester that I bought about a year before they stopped making them (2004 I think) and it has been okay but you can tell it is a much cheaper made gun and far less accurate than the older ones. I keep it in the safe mostly. It's probably had 300 or so rounds through it. I shoot it once every 6 months or so and bring it home, clean and oil it good and put it back in the safe. I only paid $275 for it at Walmart NIB. I'm sure it's worth twice that now. A good collector item because it was one of the last ones made but not much of a shooter compared to the other Winchesters or the Marlin 336.
