The Baikal is a piece of junk. I own a Rossi overland, and I had the unfortunate luck of having to fix an EAA Bounty Hunter Coach gun (Baikal). If either breaks, you will hate your life. The Rossi is a great gun but is no longer manufactured, which makes finding parts difficult and expensive. The gun has a nice finish, and is well made, but I have had issues with mine, mostly due to age and an amateurish repair done by a low rent gunsmith (not me, this was done when I was very young, and untrained).The Baikal rates low on fit and finish. If the Baikal breaks you have to deal with EAA (not pleasant) and steel so hard you can’t cut into it with anything short of a diamond bit and screws so tight you may think they are spot welds. The Baikal has an unnecessarily complex action, which is prone to failure, especially if abused, whereas the Rossi uses the greener cross bolt design with true external hammers. The barrels on the Baikal are usually designed to accept choke tubes, whereas the Rossi is improved cylinder on one side and modified on the other. Frankly I like the Rossi it is a well-made good looking gun, and I hate the Baikal. Hopefully you may find some part of this helpful. Good Luck!
Ooo, one peice of advice, see if you can "test drive" both before you buy.
