It's a solid Mauser action that is well-mated to a pretty good barrel.
the not-so-good stuff, at least on mine
- the wood is pretty, but they do not finish it well. I lightly sanded mine, then refinished it with Behlen Master Gel.
- the rear scope mount holes are off-center. I didn't notice until I mounted a NECG aperture sight. Even with the sight pushed all the way to the left stop, at 100 yards, groups were still 6" right of center. I had to drift the front sight to the right by about 0.02". The front sight dove tail now sticks out a little on the right, but the fit of the dove tail is quite snug, as you'd want it to be.
- mag floor plate closes solidly, but is slack when open (it can be moved about the Y-axis a little bit)
- tool marks
- there's a high spot on the extractor that rubs on the inside of the receiver when I work the bolt
- there aren't many choices in scope bases. AFAIK, Weaver steel bases are the only choice. The comb is low (for my face) and the Weaver bases, even with low rings, meant an after market cheek riser was necessary. And a 30MM scope will add another 2.3 MM to the height of the center line (verses a 1" scope, which is 25.4 MM). A poor fit isn't a big deal at 100 yards, but it becomes a deal at 200 yards and further.
They're solid truck guns. But don't have any doubt that I'll have no shame bringing this rifle wherever in the world I may decide to hunt. I've only got a couple hundred rounds through it so far, but haven't had any issues other than a single WLR dud primer.
For a .375 H&H, also consider the weight of the rifle. My 9.3x62 is a little on the light side, so recoil is appreciable for both the 250 and 286 gr bullets. I expect when I start working on 300 gr A-Frame loads, it'll just get that much worse. And I'm only pushing my bullets at around 2400 fps. You're going to be shooting 300 gr at 2550-2600.
Zastava wasn't my first choice, but I'm a lefty, so I didn't have a great many choices in LH Mauser actions chambered in 9.3x62.
All things considered, I'm happy with it because it's accurate and (so far) reliable, even if it has a few "warts." If you're looking for a pretty gun, keep looking.
I expect I'll bring the rifle to a smith near my house this summer to have him smooth up the action, and add some weight to the butt stock and maybe even the fore end.
