well this is my first post. I have been reading all of the awesome information on this site for quite some time and I am very impressed with how knowledgeable our forum members are. I own a .25 marauder, .25 vulcan, and got my .30 impact about a month ago. All are great guns and I am having a lot of fun with my impact. I have had NO issues so far. Operates flawlessly. Hits like a sledgehammer. Killed several squirrels and two skunks. The "pop" when it hits a skull puts a smile on my face. I have a very technical question that hopefully can be explained regarding the no limit mounts. I have not purchased them because I have not found out how to input the angle of the mounts into a ballistics app such as chairgun. Is this not possible? I rely a lot on those apps to tell me where my POI will be as I am primarily a hunter and don't want to shoot thousands of rounds just to try and re-learn my guns POI. My thoughts on using the mounts are so I can minimize my distances between mil dots. Am I thinking about this correctly? I thought about just buying and giving them a try but don't know what to expect. I don't want to lose the ease of plugging numbers into the app and not getting results that are not accurate.
using FX no limit mounts with chairgun app

I am too interested in that. I do everything on chairgun before going to the field tests. And I bought a FX no limit mount having in mind I would zero my scope using the mount and then use the mildots for distance. Am I wrong here?

If I'm not mistaken chairgun cares about the distance of your reticle from muzzle and bore axis. Bore axis is simple when using normal rings without any additional angle from items such as moa rails. Input distance from bore axis to reticle center into scope height and you should be good.

Yes, that is exactly what I am thinking. I guess I am a little confused about angles of the picatinny rail in relation to the bore axis. I assume there is an angle and that chairgun figure that in. My question is, when using the no limit mounts or any other mount where it makes the angle even more radical, how does one factor that into the input data to give you accurate info? at that point, does it boil down to trial and error?

In spite of all the input data requested by Chairgun or any other app, all variables, ballistic coefficient, wind, pressure, humidity,temperature, etc, etc, etc, I always have to make adjustments in the field. The app serves me as a basis and I really like them. When I compare the results, I usually make changes on the the pellet ballistic coefficient until the app reticle match the actual one. So, answering your question, I wouldn't bother too much on the FX no limit mount angle because at the end you always have to make adjustments. That's my 2c.

This should help
"spinj"Hey all, this is for those who plan on using Chairgun for obtaining accurate aim points and turret click values. If you are having difficulty viewing the images on your PC, hold down the "Ctrl" key and tap the "+" key on your keyboard to enlarge the scale of view (for Windows users).

That is a lot of great information although nothing is mentioned about scope angle in relation to bore. There is a lot of emphasis on just how critical scope height is which makes sense. Thanks for posting that. great info

Read this thread through, he talks about adjustable mounts in a reply to a similar question

I am beginning to get it now although have not wrapped my mind around it 100%. I have been making the mistake of thinking of scope height in relation to the bore as the distance of the center of the scope to the bore directly beneath the scope. I understand now that what is being measured is the relationship of the scope and bore axis and where those intersect (which is zero). This may be old news to a lot of folks on here but needs some clearing up to those of us less inclined to physics and geometry. I like it when I can get a clearer understanding of exactly how my equipment works to allow me to be a better shooter. Thanks again Tony and thanks to spinj for helping us understand.
