MichalS Posted April 10, 2019 Report Share Posted April 10, 2019 During the last competition I had to shoot 1000y without sighters. I had to rely on ballistic app (Strelok Pro) and my elevation was way off - 1.75MOA too high. I contacted Igor, and he suggested the ballistic solution looks OK, but my optic may be off - the click may not be exactly 0.125 MOA... Have any of You had issues with Vortex GE?

One on top of two Posted April 10, 2019 Report Share Posted April 10, 2019 If your not happy just send it back . And explain the situation and they will simply replace it with a new one. Im going to go out on a limb here and say theres a good chance it’s more you and your data that’s the problem not the scope . any problems you think you may have can easily be Identified with a tracking/ladder test ..

Michal In the good old days when I shot Target Rifle, I kept records of every shoot - wind, temp, sight-settings etc. Looking back over this data, I had 4MOA (at 1000 yds) difference between a following wind on a hot summer day and a headwind in zero temperature. !.75MOA is nothing! Don't forget, most ballistic progs are arrived at with interpolation of results rather than actual measured target elevations at every distance in all temperatures. If I had a new rifle with only the muzzle velocity as data I'd be more than happy to be only 1.75MOA high. Join any 1000 yd F Class shoot with experienced shooters with familiar rifles and ammo and see where their first shots go. Quote Link to comment Share on other sites More sharing options...

ray Posted April 10, 2019 Report Share Posted April 10, 2019 I use a Golden eagle ecr and the elevation turret is close to true, I have tested one (scr) that had an approximate 9% extra elevation on paper. A tall target test will easily confirm this. Quote Link to comment Share on other sites More sharing options...

CameronWilson Posted April 29, 2019 Report Share Posted April 29, 2019 Are both your turrets & software using the same version of MOA? TMOA vs SMOA? Quote Link to comment Share on other sites More sharing options...
Pat Allen Posted April 30, 2019 Report Share Posted April 30, 2019 I had a Golden Eagle that didn’t track properly. Swapped for another without question . No issues with replacement Quote Link to comment Share on other sites More sharing options...
No i deer Posted April 30, 2019 Report Share Posted April 30, 2019 The last 2 times I've shot at 1000yds with my 7mm saum there was 0.5 moa difference in elevation as the temperatures have climbed,same everything. I too use a vortex GE Quote Link to comment Share on other sites More sharing options...
MichalS Posted May 1, 2019 Author Report Share Posted May 1, 2019 The scope is off by around 3% Test target below - second group was shot after adding 30MOA of elevation. Quote Link to comment Share on other sites More sharing options...
The Gun Pimp Posted May 1, 2019 Report Share Posted May 1, 2019 3% is very good. Normally 5% is as good as it gets. The worst result I got for a high-end scope was 10% As the test was to be published, I gave the manufacturer (who I will not name) a chance to comment - which he did. "You are the first person to notice that." Quote Link to comment Share on other sites More sharing options...
MichalS Posted May 1, 2019 Author Report Share Posted May 1, 2019 If 5% is normal, how can anyone from the unknown distance/no sighters crowd hit anything at a distance? Quote Link to comment Share on other sites More sharing options...
The Gun Pimp Posted May 1, 2019 Report Share Posted May 1, 2019 They can't! Come to our Egg Shoot and see how many can hit an egg at 500 yds - and the distance is known and competitors have had sighters at that distance. In fact, half the field won't even hit an A3 size piece of paper at 500 yards without sighters! No one can read the wind to that level of accuracy where 5% would make a difference. You might get an accurate wind-reading at the firing-point but that reading can - and will vary tremendously over say 1000 yards. It's not an exact science Michael. But, just as you know the limits of your rifle, you should also know the limits of your scope but if say your desired 2MOA adjustment is 'out' by 5% that's an inch at 1000 yds! Do you even have a rifle that will shoot better than a half MOA at 1000 yds? Not many of us have. At our last 1000 yard benchrest comp. my best group was 5 inches - so maybe I do have an half MOA gun but, my worst was 13 inches! Go figure - 5% is nothing in the real world. MIchael maybe you need to bring your kit along to one of our shoots - you will learn a lot. Incidentally, I have two Golden Eagles. Quote Link to comment Share on other sites More sharing options...

triggersqueezer Posted May 1, 2019 Report Share Posted May 1, 2019 surely if there is a known 3% difference you would just input a new click value in your balistic program.which is the whole point of the tall target test as few scopes are exact.instead of 0.250 put 0.275 for example Quote Link to comment Share on other sites More sharing options...

MichalS Posted May 2, 2019 Author Report Share Posted May 2, 2019 "Unfortunately" the guys I shoot with are quite good at this no sighters game. During F Class natinals we have specific match that has no sighters - You shoot 10 shots per target at 3 distances (which can also vary by a couple of meters so You better measure them with a laser) and wait for them to come back... Top results are around 280/300pts on targets smaller than UK F Class. You have to rely on Your ballistic solution and scope accuracy... 11 hours ago, triggersqueezer said: surely if there is a known 3% difference you would just input a new click value in your balistic program.which is the whole point of the tall target test as few scopes are exact.instead of 0.250 put 0.255 for example What will that give me though? When dialing 33MOA for 1000y I won't be counting the clicks... Quote Link to comment Share on other sites More sharing options...
triggersqueezer Posted May 2, 2019 Report Share Posted May 2, 2019 if you dont want to count clicks use a calculator 33 - 3% = 32.01 and dial in or dial for 970 yards depending which way the known error goes. t is almost not worth it because of enviromental voodoo. i know my zero shifts from one range to another even with altitude and wind direction taken into account.

ray Posted May 2, 2019 Report Share Posted May 2, 2019 What distance did you shoot your tall target at, and how did you measure that distance? Quote Link to comment Share on other sites More sharing options...
MichalS Posted May 3, 2019 Author Report Share Posted May 3, 2019 I shot the test at 95m measured by laser range finder. Even if You assume +/-1m accuracy the scope is still off... Quote Link to comment Share on other sites More sharing options...
ray Posted May 3, 2019 Report Share Posted May 3, 2019 That works out at very close to 2% for me You have 0.6moa extra in every 30. That scope is as good as it gets. True your app using all the atmospheric variables on the day and turn on vertical component of crosswind. That will most likely improve the predictions.
