They are reliable, rugged, robust rifles, but I have to agree with Mr. James Yeager here. Your old Rem 700 or Win 70 deer rifle will outshoot it all day as far as accuracy goes.
Owning 3 Mosins, I agree with the above for the most part. However, my 1898 Tulia is pretty darn good...though still not on par with a Rem 700 or Win70.
The big thing is that the ammo is cheap, and it's very good training (and hunting) for the kids out to 100 yds with iron sights. Could accurately reach out much further with a scope, but I hate to damage historical pieces like that.
