That's funny you should mention it. A relative of mine recently found his cache of weapons. They are hand-me-downs. Some of them are VERY VERY old. 1873 Winchester for instance. There is an M1 Garand in the mix. They are in pretty good condition for the most part. But we are taking them to a gun smith to have them tuned up and ready to shoot. We suspect most have not been fired since at least the 1960s.
To get to your point, however, in a demanding position, I'd run a cloth or two down that M1, jam that loaded steel clip in it and give it a try.
Add a dozen or so weapons to those previously lost in statistics to old age. We are bringing these weapons back up to specs (just for fun and family treasures of course). They will be battle ready...er... I mean ready for the range in about a month. I'll keep these family heirlooms in tip top shape from now until I pass them on.
Before you visit the gunsmith, you should call and discuss the calibers of the various guns you need checked out. Just to make sure he has the correct headspace gauges on hand for the basic safety check.
Be warned, if you leave a firearm with a gunsmith/FFL for more than 24 hours, they have to input the gun's information in their bound book. So eventually, despite not having seen the light of day since before the '68 Gun Control Act, those firearms will enter the BATFE database if that FFL ever shuts down, or gets raided for (fill in the "official reason" for the federal fishing expedition here), or... well, you get the idea.
Make sure the 'smith checks things out while you wait. If parts replacements are required, take the guns home until the parts shipment arrives.
Hey, it's not paranoia if they really *are* out to get you. ;-)
I have reservations about taking your family guns to someone for “servicing” because then the guns WILL be in someone’s records when ,not if, the government agenys come around with their portable scanners and copies to “examine” and ILLEGALLY copy the records.
What the government (or no one else) doesn’t know you have ,they can’t tax.Or specifically come to steal.
If it were my very old 1873 win rifle, I would look for a buyer then buy a whole armory from a private seller from the precedes.
