Hi Guys,
I just purchased a howa 1500, 204 with picatinny rail, Konas 8.5-32 M30 Pro scope.
After sighting in at 100 yards I only have 10 MOA left. SUCK!!!b How can I increase my MOA as I have 35 MOA below the sight in point.
Can I get a picatinny rail which has a half degree ( 20-30 MOA ) angle on them?
Can you shimmy ( increase the back scope mount ) with picatinny rails. or rub the front mount down.?
Anyone got any options as I want to range targets and dial up the scope for hits.
cheers

Well, you started with a scope that has only 50MOA total adjustment to begin with. There are few places out there which supply Picatinny's for the HOWA... I can't remember EW(something F or G, think) is one.
I've not seen or used a Konus scope, but your post indicates you have less total adjustment than advertised. I've looked around at the info on them sometime back. Happens sometimes, even in better scopes, but the tendency for the better ones is to be conservative rather than overly optimistic. You didn't state what your intentions are for that scope/rifle combo... varmints, paper. A 20 MOA rail should give you all the distance you will ever need... with that lightweight bullet, wind is going to give you more problems than getting to distance. OOPS... looks like EGW, which is, BTW supplied by our very own SWFA http://www.swfa.com/c-2726-weatherby.aspx (I was close, it had an E, a G, AND a W in it... just wrong order). It is the Weatherby Vanguard Rail (Vanguard made by Howa in Japan).

You sure there is not a problem with how the current rail is mounted?

Good point by Silver, I just made the assumption you would have already checked that.

thanks for the comments.
there is 4 and a half rotations downward ( 4.5 x 7.5 MOA ) = 30-35 MOA and only 12 above , so yes all the advertised MOA is there.
I wasnt worried about the "only 50 MOA" as yes, its just a small bullet and I dont need alot of MOA , perhaps 10 if Im going for it in good conditions. ,, I dont like to wind scopes near there end point thats all, as I feel that might not be good for their overall durability.
I varmint with this gun but like to target with it at longest distance, this builds my confidence at varminting at long range.
So as I gets this gun set up properly I would rather have the scope set in mid MOA if I could.?
HAve you any solutions to help as I have very good range finder with My TRG 42 and being very successful with ranging and dialing up at long range and would rather do this than just hold over.
cheers

Remove the mount, check to see if it is, in fact mounted in the proper orientation, make sure there is no "warp" in the mount, make sure there is nothing under the front end which would slightly raise the front. Front should be torqued to 20-25 INCH/lb, other screws 25-30 INCH/lb. If those actions do not get you to a better adjustment range, then a 20MOA base should do the job.

It is very common for things to have a slight taper. What happens then is the rail also has a slight taper. Well, for what ever reason the wrong end of the mount or rail gets installed "backwards." This is a common problem and produces the problem you have indicated.
Rifledude here may be able to tell you if that is the case. He has been slamed lately and may not get to this question. If EGW makes the part, then George could tell you for sure. A brass shim between receiver and rail is a short term fix (disimilar metals) if reversing the way the rail is mounted does not change things or will at least tell you if you are headed in the right direction.

If the base seems ok and is mounted to the rifle properly, another quite satisfactory option is to replace the rings with Burris Signature Zee rings, which have a very clever system of offset inserts, (sold seperately in 1-inch, packaged with 30 mm., or so I'm informed) which allow windage and elevation adjustments to the tube itself, within the rings.
They aren't perfect; you have to slide the rings lengthwise to get them on and off the base, rather than just loosening the nut and tipping them off like Weaver-style rings are supposed work, but they're pretty good, otherwise. Not a real Tactical system, though. They aren't as rugged as Badgers or TPS or something like that, though plenty tough for target and varminting, as well as 90% of big-game hunting.
