    I mounted the scope and bore sighted the rifle Friday. It took only a few clicks at the indoor range to have it print 1/2" low at 25yds which would zero it at about 200yds. However, I now only have 5MILS of elevation before it tops out. Hornady's standard ballistics calculators tells me that with a 200yd zero, those little 55gr bullets will take another 4.2 MILS to get to 600yds and a just a little over 14 MILS to get to 1000yds. So, I am running out of elevation. I do not think it is the scope. I am going to install low (.250") Warne rings in place of the medium (.375"), however, I do not think that will solve my problem. The scope will be closer to the bore axis which I like. I need a little advice from any of you rifleman who have had this problem. Some of the solutions that I am aware of are: shimming mounts/rings, buying a difference mount with built in elevation, using the MIL dots for longer range shots and just not shooting beyond 600yds. Help please.

    Skeeter, EGW makes REAL nice rails for the the MVPs. They come in 0 degree and 20 moa incline. They are a little longer than factory rails and hang over past the the front ring. They are money well spent in my opinion.

    You don't describe what mounting bits you have on there or what kind of scope so it's hard to help that much. I'm betting you have a minor bit of error in the machining/assembly on your gun. Haven't seen that on MVP's so far but there's always a first time. I have this problem ALL THE TIME with browning rifles.

    Chucker's right. You want to start with a 20moa base. If nothing else the factory scope mounts are not very good, bordering on garbage (IMO). That will pull your zero down 5.8mils. 5.8 mils isn't much though. That's enough for about 500-700yrds depending on ammo selection. If you want to be able to reach all the way out to 1000 you need around 30-40MOA of elevation travel available. Holding off for elevation is a good capability to have just in case or for medium range hunting but sucks for precision compared to a proper cross hair directly on the center of the target.

    If you have a 1" scope tube then I'd recommend these:
    http://ads.midwayusa.com/product/416175/burris-1-signature-zee-weaver-style-rings and you'll want to grab http://www.midwayusa.com/product/71...fset-inserts-installation-kit-005-010-and-020 as well so you can dial in exactly as much elevation as you want/can. I like to have my elevation turret dialed to just a few minutes off the bottom of its range so I have all the up remaining.

    For 30mm tube:
    http://ads.midwayusa.com/product/719934/burris-30mm-signature-zee-weaver-style-rings-matte same thing. The 30mm include 10MOA inserts so you don't have to buy extras.

    For 34mm tube:
    http://ads.midwayusa.com/product/686977/burris-xtreme-tactical-signature-picatinny-style-rings-matte . These come with 5,10,20moa inserts.

    between the 20moa base and the rings you'll be able to dial whatever you want.

    If you can post pics of your scope setup as it is now we can look it over for assembly fuggups.

    Thank you for your information and advise. I did not know just how prevalent this problem has been in the past. I have a new Winchester Extreme Weather SS caliber 7mm-08 rem and the Talley mount/rings and 4x12x40AO scope installation was quick and easy with good remaining elevation. That rifle cost twice as much as the MVP. Since I really like the Warne rings, I am going to buy and install the EGW base mount with built in elevation. I know that pushing that little bullet to 1000yds is ridiculous and when it goes through its transonic phase it could end up in the next zip code. I do have 200rds of the 77gr sierra match king ammo but I don't think a 1 in 9 twist rate will stabilize those bullets. It will also go through the transonic zone before it gets to 1000yds and could wobble off target. It will be interesting to see if those 77gr bullets will keyhole at 300yds. I appreciate your help.

    Thanks for the advise. I am familiar with EGW mounts and will verify that the Warne rings which are made to fit weaver base mount will fit on the EGW picatinny mount.

    You can put weaver rings on a picatinny mount but not picatinny rings on a weaver mount.

    1000yrds with a 223 ridiculous? Naw. I do it all the time in competition. The 9 twist will stabilize 77's in a 24" barrel but I'm not sure about a patrol length barrel. Going to say probably on that but just barely. Shooting through the transonic region is mostly going to be a problem when you over spin your bullets, they don't nose over when they're overspun. If you only get them marginally stable with an Sg of 1.3-1.4 then they'll tend to do better going transonic and won't keyhole at the long end.

    The 1:9 could be able to handle 77 grain bullets but every rifle is different, so your mileage may vary. It wouldn't hurt to give it a try just to see.

    You didn't mention which model of MVP you have. If it's the short barreled Patrol like mine, 1,000 yards might not be obtainable. I'm figuring 600 yards would be the limit with the 16" barrel. If you have a longer barreled model, you should be able to do it.
