When we moved from Oregon to Texas was the first time I have ever paid to have someone move my stuff.
I went with a national moving company. I had a binding estimate. They moved the safes, with the firearms inside. They would not touch the ammo, powder, and primers. We moved all that in our Tahoe. I'm really glad I didn't have to move the firearms as transferring 75+ firearms from the car to the hotel room twice a day would truly suck.
My firearms are insured through Eastern. $140/$40k of coverage.
I just wrapped the guns up real well, made sure they couldn't move and let them have at it.
The binding estimate saved me a ton of money. When he came out for the estimate I gave him weights for all the odd stuff like 5 gallon buckets of brass, 5 gallon buckets of bullets. Weight on the safes and so on.
Turns out he was 4,100 off on his estimate. They even called to ask if I had added stuff after the estimate as he was normally within 2-3% of weight. That binding estimate saved me several thousand dollars.
