Kenny,
I bought an optics a month ago, because I was told is a good scope at the local store.
I ordered and got a Nikon Monarch 5-20X44 SF 8424 for $350 . It is refurbished with warranty, and I think is brand new. I didn't know when I ordered tactical, and hunting scope a bit different, so I 'm not sure I did a right thing or not. If you have a suggestion, I will appropriate that. I can sell for $350-400 on craigslist.com easy , and will buy a different one. Still planning to shoot at 600-800 yards
I think that will be fine. It seems to be a decent compromise between an all out long range target optic and a hunting optic. A little more top end magnification would be nice, but 20X should do well.
The ideal situation would be a separate scope for targets and another for hunting, but if you are only going to have one, that seems good enough. I feel that a low of 5X is a little high for hunting, but I hunt in New England, and I am unfamiliar with the terrain in your area. If your shots will be from 50-200 yards, I think a 3-9X scope would be better for hunting. But if you will be shooting 100yds+ minimum, than the 5X will be great. You could still use the scope you have for targets if you like, as you can get a good hunting scope for $100-150. You don't need absolute top line, just clear optics and something that holds zero. I have a used Bushnell on my 30-06 that I paid $25 for, and it hasn't lost zero with over 250 rounds and being lugged through the woods and bumped and banged. I also believe Bushnell has a lifetime warranty as well, though I am not sure. But their scopes are affordable and will get the job done very effectively.
One problem I think you may run into is being able to adjust your POI from 800yds down to an acceptable zero for hunting, such as a 100-200yd zero. I believe you may have to run a 20MOA base for shooting at 800yds, as you may not be able to adjust the scope enough to get a zero at 800yds. If you don't know what a 20MOA base is, it's a scope base that is tilted slightly downward at the front, which will aim your scope 20MOA downward, so you don't use all of the adjustment of your scope to get an 800yd zero. I am very unfamiliar with shooting that distance, so I am unsure if you will need a 20MOA base or not. I'm sure someone else will know more than I.
So having a separate scope, rings and bases for hunting would probably be beneficial. But make sure you get very rugged rings and a 1 piece scope base, as they are very important. You want the mount and rings to be as solid as possible, as any flex will show up big time at 800yds.
Also, you will want to "lap" and align your rings. Here is an article on how it's done, along with the proper tool to do it. You will notice the alignment tool has flat ends on the tool. That is what you want, the tools with pointed ends are JUNK, don't use them. They do not align anything properly. If you know someone with a machine shop, or there is one in the area, you can probably have similar stuff made for short money, but it could go either way. Or possibly find a gunsmith in the area that will do it for you, or let you use the equipment to do it.

If you were to go with a separate scope for each application, this is what I would go with for a target optic:

The Weaver T-Series are some of the best lower priced target scopes going. I have been told by several people on the 6mmbr.com forum they are the way to go for a budget target optic.
Now for hunting, I would go with one of the following:
These two have illuminated reticles, which are visible in very low light. They are really good for early morning and late afternonn, when you wouldn't be able to see the crosshairs in a standard optic. I have used them previously while hunting, and they are just awesome. Really helpful.

The lower two are designed to have good light transfer in low light situations, such as dusk or dawn, when it can be difficult to see through a traditional optic.

This one has additional aiming points out to 250yds, which will be great for holdover on long shots while hunting, as you don't often have time to be twisting turrets.

Sorry this is a mile long. I hope it helps though.
