Ya know, I hear all this crying. Back in 2009 I had heart surgery. Think 15# lift limit. So while I was recovering, my wife decided we needed a new house. One thing an idle mind is good at is making excuses. The doctor provided the ideal one. I can't lift stuff.
It was OK, our sons said they'd do it. So we started boxing stuff up. As in ammo cans. Needed to go to another gun show and buy even more. No, not like 5 or 10. Like dozens. So my younger son began hauling all the stuff from the old basement. I even gave him one of my safes to protect my guns during the "move". No, I didn't want it back. But he did make a bunch of trips to his basement.
Then the new house was built. Same site, the wife just had the old house knocked down and the new one built. As I was healing and doing rehab. So we moved. Younger son again hauled all the stuff up to his garage, and then from his garage to the van and jeep. The vehicles were grossly overweight, but I was still officially recovering. I had time so I drove slowly and carefully.
Got to the new house and drove the jeep around back. From the back of the jeep into the "burglars" entrance/basement door. Sure, lots of lifting but then setting the stuff back down. On my little 4 wheel cart. Then rolling it to the gun room. Took the jeep back up to the van and transferred a load. Repeated the same drill, over and over. Son had done what I needed, and kept making excuses that he'd come and help. He was hurt. Got the remains of the stuff (handloading isn't your friend when you move). Got it in place easily. Son asked how I'd done it. Easy, wheels are your friend, or mine anyway.
So when I croak (maybe sooner than everyone thinks) I've got a gun room full of heavy stuff. Really heavy stuff. But I don't have to move it again. And I don't have to move it again. If they want to inherit the stuff, they've got to come get it and haul it away. Then find a place in their houses to hide it or store it. No longer my problem.
I read the threads where someone says they've got enough to shoot for the next year. I think those guys are seriously out of ammo.
Those that discover lead is heavy should just wait till they move again.
You can store enough primers in a plastic tub to shoot for a decade or two. You can store enough powder to shoot about the same length of time. Empty cases aren't too bad either. Bullets are where the weight seems to be concentrated. Loaded ammo is heavy, unloaded bullets are a real pain, but not expensive if you compare them. You can stuff more bullets than you can carry in a 50 cal can. More than you want to lift in a 30 cal can. I speak the truth, listen if you want. Or suffer the pain of discovering it yourself.
