I'm sure to get what I need to keep it legal and then ship the firearm to the buyers FFL myself. I NEVER use an FFL to ship my firearms.
I don't know how you guys ship things, but I take up to 1 1/2 hours to carefully bundle and package up a $600-$2,000 rifle that I am shipping....especially if it has the tradtional stained-finshed wood stock. My rifle gets a hefty layer of white foam board in front of the barrel and in back of the buttstock, and often I cut and fit 1/2" thick wood barriers on the barrel side of the box so the rifle barrel doesn't poke through the box like a ramrod. The rifle gets foam and bubble wrap everywhere else it's needed, and loose items like magazines or bolts are wrapped and stuffed firm in the box so they don't slide around in the box and scratch or dent the rifle. The package then gets a protective outer cardboard box around it. I finally seal all box joints with brown paper glue tape. DO YOU THINK THE GUNSHOP THAT YOU WOULD HIRE TO SHIP YOUR VALUABLE RIFLE REALLY CARES LIKE YOU DO?!!
Big plus one.. I pride my self on my packing. I bought a Sako heavy barrel from an older gentleman thinning out his collection, he shipped it in the original box, nothing more, with two sheets of newspaper wrapped around the rifle. It arrived broken clean through at the wrist, a real heartbreaker. It worked out OK for me in the end, and his insurance covered him (!!), but to see a lovely old piece like that in that condition....why take a chance.
