Oh! There's much more input on week-end. Thanks everybody.
since you said "battle rifle" scenario, i would say NO SCOPE at all- in a battle scenario, your scope, being lenses and tubes, whatnot, is going to fail at a most inopportune time-... you're better off with a good range table notebook that you've worked up yourself-
I get your point. I made my homework and practiced with my irons. My eyesight is pretty good, I got good results up to 3-400m.
Last fall I hunted moose with M14 NM irons. I noticed that I could have shot almost 30minutes more each day with a scope. At dusk/dawn you can't really see your post and ring.
Most M14 in Afghanistan and Irak are wearing glass. I take this as a clear statement that a scope can be effective and rugged.
What about a US Optics SN-3 1.8x10 scope with a Mil-Scale GAP reticle and 1/10 Mil elevation and windage knobs ? As tough as anything out there - anything. Expensive ? Yes. Flimsy ? No, not really ...
Good idea. That or a JMG MOA, the illuminated donut must be nice at close range.
But for this scope I just prefer a BDC reticle like the Burris XTR where you don't need to count clicks or mil-dot. This rifle should be fast and simple. I don't want a calculator, an angle indicator and a Kestrel. It's not a sniper rifle. I'm looking for 600m, not 1km.
I already made a little ballistic table and I understand it's the way to accuracy. But after you have your table, you still need to factor the atmospheric conditions, the elevation, etc.
I don't think seeing a quality 1-8 under 2000 will happen just yet.
Swarovski glass is most likely the clearest and bushell really do make a good optic, not maybe the greatest battle optic but good nonetheless.
In your last sentence, do you mean Swarovski don't make the most rugged scopes? I noticed their website was talking only about hunting, not even LE applications...
what's not being addressed is the fact that if you put a highpriced scope on a m14 is 1) it's NOT CAPABLE of justifying the cost with accuracy- not like a bolt gun
2) the "DOUBLE PUNCH" of the action tends to tear most scopes to pieces sonner or later- it's a LOT harder to replace a high cost scope- that's WHY the bushnell elite 3200 is kind of the norm for the m14
1) I guess on your bolt-gun you enjoy a great scope because the gain in clarity and repeatability allow you to group better.
In my case, the assumption is that a hi-quality glass will perform better in low-light and be more rugged/reliable. Eventually it will also be a gain in versatility with 1-6x / 1-8x scopes.
2) I didn't hear of many scopes falling apart on the M14. My understanding is that nowadays hi-quality scopes designed for duty use can withstand the recoil of a .50BMG year long.
At what point is money being spent unnecessarily? There are some outstanding scopes out there. But just how expensive a scope is really necessary? Obviously a scope must be clear, bright, strongly built, and reliable. If it won't hold zero, it is a waste of time.
For the use suggested, a variable that goes as low as 2 would be nice. Upper limit of 7-10 power would be great.
We all learned that you get what you pay for (generally). I agree with you that at some point on the price spectrum, the little extra quality becomes too expensive.
So for now I'll settle on the Burris XTR 156. It's features and specs are perfect for my needs and it should be a good bang for the buck.
In a few years if I feel limited by it, maybe Nightforce, USO or S&B will make a scope that I'll dream about.
