While I hear Bud's has a good rep, I would shy away from a purchase like this online. Bud's does not inspect prior to shipping. By that I mean, you (and they) make no selection other than whoever reaches up on the shelf and grabs a random box. I have contacted them in the past about Winchester Model 70 Supergrades they've had for good prices. The problem is...some Supergrades have stunning wood, some have "blah" wood, and they are all the same price at Bud's. I didn't want the "blah" version! They were emphatic that there was no option to "hand select."
With a Mosin, I would not take "luck of the draw". These rifles were made to be abused, basically. That's what the Russian mindset in weapons design was....that anyone, literate or not, skilled with firearms or not, could make the thing shoot. It was not made to be elegant or classy, but to work. They were shot by folks who had no clue, really, what they were doing with firearms maintenance, and they shot corrosively primed ammo to boot.
When I bought mine at Cabela's a few years ago, I drove the gun counter guy nuts. I asked for one, inspected it and rejected it. He brought out another. And another. And another. I think I went through 6 or 7 until I found one without buggered up wood and with a strong looking bore, as well.
My persistence paid off, as the one I owned shot Tula steel-cased ammo into 2" groups at 100 off the bench, which is pretty decent. I'd bet handloads would have shrunk that a tad, but even so, that's not shabby for what the rifle is. They are not known to be tack drivers.
With a potential a savings of only $30-$50 by going online by vs. in a store, I'd personally get one that I could inspect in person, rather than luck of the draw, but that's just me.
