Someone suggested in an earlier post on magazines, and not being able to be fully loaded. My dad still uses grandpa's Win 100 in 308 every deer season. He has 2 magazines for it, one I believe is for a 284 and the other is a 308 mag. I know he can't load them to full capacity or it jams up on him. I have only shot the gun a few times, it has alot of sentimental value to my dad (and me), and I don't want to use the gun and have something bad happen. I'm not sure if he has cleaned the gun in 20 years, he wipes it down with oil after using it, but has never cleaned the action. I have seen his go full auto twice over the years. That is always interesting when that happens...LOL
