If you use adjustable mounts and chair gun how do you get the 2 to work out, I use the adjustable mount to make up for lack of scope adjustment at longer range to use million dots. Example with verminator zero at 50 yds chairgun might say 20 yd is same as 50 yd but it is actually 2 miles dot hold under. When scope is level chair gun works great.

Chair gun question for adjustable mounts.

There was a thread about this a while back. Maybe do a search. I seem to recall that it was decided that the objective lens height was the number to use as that is where the image enters the scope. The eye piece will be a bit higher. In other words measure scope height at the Objective lens to get your number for the app.

You, know this has been bothering me since I started playing with chairgun again.
It would seem that the 2 most important factors to me are left out.
1 - The angle of the scope in relation to the bore.
2 - How far forward or aft is the scope mounted in relation to the barrel crown (not shroud).
I beat myself up for an hour, " trying to solve the math", and decided that chairgun is at best and estimate and the best way to "know YOUR gun" is to:
1 - get a chrony and check fps at different distances. Then write down the results.
2 - after zeroing, shoot targets at various distances and write down your own trajectory.
Then I popped a top on a cold beer and enjoyed the rest of the night.
You won't get benchrest quality out of chairgun.

You hit the nail on the head Jlands. The only way to know for sure is to map it out yourself.

Yeah on my Bobcat chairgun works perfect, the scope is level and from 10 to 120 yds it is spot on. On verminator scope is lower in front higher in back to make up for elevation at lower power so I can zero it at 50 yds the distance in my backyard that I take ground squirrels and rabbits raiding the garden. So basically the pellet arc intersects the scope close to the barrel and again farther out making chairgun useless. I'm going to level the scope out because using the mildots is difficult in a pesting situation where I'm shooting anywhere from 10 to 65yds. I ended up getting my holds for every 10 yds and it is too wacky to remember quickly.
