I am knew to this game (again, kinda born again) and recently acquired a Savage 12FVSS in .308. It shoots very well but I whish the replace the Leupold bases and rings. I'd like a sigle base that gives me 20MOA of elevation or maybve 30MOA to use in cunjunction with Burris rings with inserts if more elevation is required.

I currently have a Bushnell 10X tactical which is getting replaced with a Busnell 4200 6X24X40 mildot.

I am hoping to reach 1600 meters with regularity and some accuraccy.

Any recommendations on bases and where to get them? Let the CGN floudgates pen!!! (I am currently waiting for my sleeping pill to kick in and am "aiding" it wit lotsa liquor, very slow tipyng...).

Thanks fellow CGN'rs

Shooting a mile with a .308 might be a bit optimistic, but the bases you are looking for can be had from Near Manufacturing, Badger Ordanance, Warne, Kelby, Night Force, Farrel, etc. Order a catalog from Brownells.
 
The scope you are planning on using I do not think will adjust enough for the distance you are planning, even with the 20 MOA base. You need something with a 30mm tube and higher turrets.
 
Tactical Precision Systems (TPS) make very nice bases and rings. Unfortunately they have limited rifles the bases fit. Fortunately, Savage rifles are not a problem.

They are available in steel and ultra strong Aluminum 7075!

They (TPS) are also made to 1913 mil spec. Farrell makes nice bases as well but you have to special order mil spec. The standard supply bases are made for the smaller cross bolts (Weaver etc.). They work fine. The biggest complaint is the base is relatively thick which can be a problem if you want to mount the scope as low as possible....
 
I've recently aquired an EGW base. seems well built and i'm happy with it. was around the $50us mark by the time it hit my door. quite a bargin compared to some bases.
 
The biggest problem you will face is scope elevation adjustment vs the drop of the 308. There is no way to go from 100yds to 1600yds using reticle and turrents with the 308 no matter how you shim that 6X24.

The best you can do is set up so that the very top of the reticle with full down elevation is somewhere near 1000yds (you will need to plot your load into a ballistics program to see how much elevation you will need). I am going to take a guess that you will need 40 to 50 MORE mins of elevation travel from 1000yds to get to 1600yds.

The 308 simply drops too much beyond 1000yds for that scope.

The Elite 3200 10X would actually be a better scope because it has about 80min of adjustment and you can use the 36 from the reticle. Now you can shim the scope for a zero around 200yds and make the journey out to 1600yds. Or the same way out there zero and keep going further out (est. 15 min per 100yds past 1500yds).

If you don't mind a very LR zero, you need to first shoot the rifle with the 6X24 to find out how much shim you actually need. From there, add a base and/or Burris rings and reset your zero for way out there.

For MOA bases, I have been using the Farrell base for several years and don't see the need for 'better' or spending more money. I use their alum base and have had no issues with peening - a strong alloy.

Do loctite those screws. I had some real fun a few months back chasing ghosts in two rifles. Loose scope base screws.

Anytime you want to get that rifle set up, just let me know and we can go shoot. Definitely have the Burris rings and the extra ring insert kit.

By the way, there is little problem with the 308 going to 1600yds (just use the right bullet). Wind drift can be severe but it can still be very accurate. There is a club in the US that shoots them to 3000m. Big target drawn on the desert floor.

Think Artillery. Some fun....

You can have an extreme base system made which will do what you want. It would be very radical and won't be recommended but I have seen some posters do some odd things so the sky is the limit.

Alternatively, you could replace the rig with a 338 Lapua or some other fine long range cartridge... Using Lapua brass you can push the extremes..

There is a story about 3000 yard shooting in "Precision Shooting at 1000 Yards". The scope is mounted at a steep angle very high above the bore. The cheek piece has to be raised almost 6", but with a .308 AI the guy made a 3000 yard hit on a 16" gong with a 220 MK @ 2400. Interersting exercise, but the rifle would be useless for anything else.

Ken farrell makes a 30 moa rail for savage model 12. I got mine from Sharpshooters Supply in Ohio. Lisa would be happy to mail you one.
 
Bases MOA

I have a Remington in 308 and the same scope. I put a Near 25 MOA base on my rifle and I can't sight in the rifle at 300 meters but you would have enough adjustments for 1000 meters. I think you would have to install a 10 or 15 MOA base in order to zero at 300 and also have adjustment in this scope to hit at 1000 meters. I don't think it would work to 1600 meters. I am afraid you will need a 30 mm tubed scope with enough adjustments. FYI, Steve
