High Power rifle/scope question

[SPRTN308]

So, after a season of getting into smallbore, I think I'm going to dabble in high power this season with my model seven .308. My question here is that I'm going to need a dedicated scope for this setup, but I also plan on swapping out the scope I use for hunting. I'm planning on doing this via a weaver rail and detachable scope rings.

The thing is, with the amount of drop I get with the .308 at 500 yds, will a scope with 68 MOA cover me for adjustments out to that range? 68 MOA means I can adjust for a total of 68 inches, but that includes both directions.

For smallbore I ended up picking up a VXII 6-18 target. Would this do the trick for high power as well, or do I need a rail with elevation built in?

Someone help me out here please.

That scope should work great! You may want to check with Leupold, though.

You may have to put two layers of beer can in the bottom of the back ring to make it. My 30mm tube Leupold gets me out to 1km.

That 20 inch barrel combined with heavy bullets for 500m ram shooting will require you to do some sort of shimming even with the VX II Leupold. If you use the one piece Weaver base you should shim the single screw rear with at least .010 to .012 metal. Fill the gap created at the rear most front screw with shim metal to avoid flexing or bending the base. This will keep the rings pararell and aligned with the base. You basicly have created your own MOA style base. Go out and try reaching 500m with your chosen load. If it still wont reach, increase the shim thickness.........or add more powder.

Since weight isn't going to be an issue, you could use a set of Burris Signature Zee rings. These are for Weaver style bases.These have an offset kit you use instead of shimming your base. The offsets are made of a composite material and will not mar or scratch your scope. The offsets come in .005,.010, and .020 sets. These will be a little more money than shimming your base but I prefer this over shimming anyday when at all possible.

I like the Zee rings a lot for the reasones you outline Butch, but they are heavy (the rings are steel) and I had worried about them standing up to high power. If your rifle makes weight with them and they handle the recoil, they make a great choice.

[Heavybarrell]

Yes, they are heavy. But Sprtn states they are going on a Model 7, these are very lighweight rifles. As far as holding up, I have them on all my hunting rifles 270win, 300 win Mag, my 6.5 long range gun and various 260's along with others, for years and have had absolutely no problems with any of them. I would have them on my Sil. rigs if there wasn't a weight problem.

Thanks for the information!

Hmm. Okay then. I think I have my setup figured out then. I totally forgot about the burris rings and their inserts. Silly considering I have them on my CZ (standard inserts though).

I'll just pick up two sets of burriz signature zee rings and put a weaver rail on the model seven then. I have to wonder about these $7 dollar rails though and just how solid/secure they are though. At least this way I can simply change out my optics come hunting season, and I'll all set.

Thanks guys.

Now I should probably look into bedding the action properly.
