[QUOTE="eshorebwhntr, post: 980680, member: 17112"] Definitely possible for any scope, no matter make/model/price range to be slightly off. To check it, put up a large paper target at 100. Shoot a group at 0. Dial up something extreme, the more the better, but keep it on the paper. Usually 20-30 moa is good. Measure how far it tracks with a tape measure as accurately as you possibly can. From these measurement you can find out what your true click value is and correct for it in Shooter under the setup option for each particular gun. Example: @100 yards, you dial 30 moa. You measure that the impact from center to center was 35 inches. 30 moa @ 100 yards = 30moa * (1.047in/1moa) = 31.41 inches Acutal movement = 35 inches % Deviation = (35-31.41)/31.41 = .1142 = ans*100 = 11.42% off In shooter the correction factor default is 1.0. For the example above the correction factor would be updated to 1.1142. As for the other problems you are having between Shooter/G7/Exbal. I've never used Exbal so I can't help much there. I've used Shooter and G7 a fair bit and like others I have drops consistent within 0.1 moa over a long range. You might want to check how you are entering the pressure in each setup and how each setup is using your entry. On shooter, if available, I typically use the information that it pulls down from the weather station and GPS. If you are entering this manually make sure you understand what is going on in each program. In shooter, you can do 2 options. If you are running a Kestrel at your location you can pull the pressure reading off of that. Just make sure to check the box for "Pressure is Absolute" if you do that. The other way to do things is to use the relative pressure, which floats from 29.7 for ****** weather up to 30.1 for really nice weather, in conjunction with an accurate altitude entry that shooter will then use to correct the pressure (based off of standard altitude vs air density tables). For instance, where you are in Worland, wy is probably about 5000ft. So the BP should be around 24.5 (that's what I used in Rock Springs when I use to do air flow calcs at the power plant anyway). Right now the internet says the BP in Worland is 30.09. So if you were running shooter right now, you would enter in the elevation of 5000 and the pressure as 30.09, and don't check the box for absolute pressure. The kestrel way is best, the other way will get you pretty **** close in my experience. Like someone else mentioned. Check that the powder stability parameters aren't wrong. That could be throwing things too. When I've input all parameters correctly into shooter I've had really good luck with it. I hope this helps get you something that will work. Good luck. [/QUOTE]
