I'm thinking 4x33 Leupold , or maybe the 2.5-8 ?
It will go on a .375 Zastava

Castle Rock--check your PM.

Tasco World Class. When I went to Alaska the first time I put a Tasco 4-16X40 on the .300 Weatherby and the .375-.416 because it was the only rifle scope I never had a problem with.

2.5x Leupold or the 3x FX-3. The Leupold fixed 4s and 6s are pretty damned bomb proof, too.

Interesting...a Tasco World Class 3-9x40 is the only scope I have ever owned that crapped out on me. My dad has one that has been on a 30.06 for 20 yrs(course he only shoots it once a year). I bought one to go on a 7mm Rem Mag and it lasted less than 50 rounds(went fuzzy and reticle fell apart). Started buying Leupold and Burris(made in USA) scopes after that and haven't had a problem since(20+ yrs).

Castle Rock,

I think you're on the right track with the Leupold VX3 2.5-8x36.

Tasco World Class scopes have varied considerably over the years. At one time they were indeed very tough, but all the present models retail for under $100, and at that price they certainly aren't among the world's toughest scopes. Personally, I might put one on a rimfire, or maybe a .223, but not anything that kicked harder, especially if I planned to shoot the rifle much.

My vote would be for a fixed-power Leupold.

Tasco WC and Leupold 2.5-8x's..... Not so much.



For a pure hunting scope a fixed power Leupold. For a scope with the size/weight that can be used on a hunting gun a fixed SWFA SS.



It depends on whether size and weight are the overriding factors or durability.

Leupold

I wouldn't know what's best for the cost. But a fixed power Leupold is a good bet

Leupold 2.5x Ultralight...

I've had a Leupold M8 4x for quite some time, first on a .45/70 and since then on my 9.3x74R double. I've never had any dramas with it, but there again I think I've only had three scopes fail on me that I can recall (one a Tasco WC, incidentally). The fixed-power scopes do at least theoretically have the advantages over variables of greater simplicity - less to go wrong - and fewer lenses, which may allow better light transmission and lower weight, all else being equal.

The little 4x Leupold certainly seems to me to fill the bill for for a light, compact and rugged scope on a medium bore. YMMV.

I've been hammering a VXR 2-7 atop a Steyr carbine for a while now. Rifles 8#, pushing a 270 gr over 62 g imr4895 to 2510.
So recoil is certainly present.
The scope has not shifted a click. Bases are Maxima's and rings are qrw.
My 270WBY wears a 4-12 varix and has never had any issues, but its shot much much less frequently that the Steyr. Still, its been going since 81.
A scope is a fragile thing compared to what its strapped onto. Over time, temperature changes and miniature high pressure explosions underneath it, something's going to weaken.
Buy right, mount correctly, don't abuse. I'd expect 25 years from a newly manufactured scope.
Products just are not made to last as long as they once were.
Some of those B&L scopes are still running as strong as the day they were unboxed.

Leupold 3x, 4x or 6x would be first choice for me for your purposes. I have no problem with the 2.5-8 either. Hope you tip something big over with that thing!!

I've had very good luck with the Sightron S2 3x9 mounted on a Ruger 30-06 carried afield by my son and nephew who seem never to miss a bush or tree on the trail. I cant imagine a scope that wasn't deliberately tortured going through more punishment in normal hunting. Between 100 degrees or higher for coyotes and below 0 for elk, below sea level to over 10000 Ft. and unnumbered drops and bumps it stays zeroed.

I recommended the scope to my clumsiest friend and he has had it on a little 243 for over 10 years without screwing it up - very rare for him. He thinks it is quite boring, my idea of what a hunting scope should be.

One of my hardest kickers is a Savage 10ml smokeless. I am running a Barnes 250 gr. with a considerable load of IMR 4198 that I got off Dougs Message Board. I have not chrono it but it supposed to be running @2200 fps. Recoil is significant to say the least. My VX2 3x9 has not moved a dab over the last 15 seasons. It is consistently spot on everytime I go to the range to test before the season starts.

4x or 6x weavers have never given me any concerns and my 4x IOR has been on either a .458 or a .338 for the 20 years I have owned it and never an issue. Now is on a 7x57 and will likely stay there til I die.

P.S. So times you can find used Zeiss 4x that are well priced
