I've found lots of good deals on auctionarms and gunbroker, but I probably spend about 10 hours a week checking the sites for various things. Primarily, I am interested in bolt action sporting rifles, but occasionally I pick up a decent double for myself. I am learning how to make minor repairs, and Dale Edmonds
is teaching me to refinish Damascus barrels. Here is one such item
I picked up about a year ago, the stock cleaned up nice, as did the
metal, and the barrels should be done soon.

I don't really like it when sellers start their guns at prices far higher than what I think they are worth, but I see that all the time at gun shows.
