    Here is a five-shot group (no mulligans) shot at 145 yds (the limit of my mil-dot scope) with my Chairgun holdover (8" Shoot-N-C target). It was shot outside with a slight breeze. I used a Daystate Pulsar HP .25 shooting JSB Exact King 25.39 gr pellets. My full-bottle regulated (45 shots) shot string for average fps input to Chairgun was performed with a Chrony Master Beta. I weighed a random out-of-the-tin 10 pellet sample size for an average pellet weight of 25.40 gr (SD of 0.31) using a Diamond digital scale (0.005 gm), which is what I used for the Chairgun pellet weight input. I zeroed at the Chairgun optimal zero range distance using a Caldwell Magnum DeadShot FieldPod. I used the tinfoil method for determining scope height for input to Chairgun. I used the listed Chairgun BC of 0.0360 for input. (Now that I have a DeadShot, I plan on doing practical field tests for BC using the POI at range method.) I shot this group with my Primos Tall Trigger Stick tripod w/ a two-point rifle rest attachment, which is what I use for hunting. Yo, science baby!

    Nice! Question: Was your mission hitting the paper or the neighbours container?

    Question: do you know thats his neighbors container or just an assumption?

    I would keep your range shorter so there is a small group, I don’t see any group there really just a scatter. 

    No idea DeadEye, I see a fence usually that’s a boundary.

    Ha ha, milacik! Both! I had to use the container to take a range reading, because I couldn't get one on the target at 145 yards away. I got close enough to the target to get a consistent bounce-back and then took a reading on the container at that same distance. I used the difference to calculate the range on the target at 145 yards using the bounce-back from the container. (FYI, the container is junk. Besides, it was seeing only 16.3 ft# at 149.9 yards anyway.)

    Actually, I thought the whole exercise would be moot because I didn't think I'd hit paper anyway. No one was more surprised than me when I saw a yellow splash on the first shot!

    Oh yeah, milacik, I did that just for shoots 'n ladders. It is the limit of my optics. I wanted to see how accurate my Chairgun numbers are. My group would be tighter if I would have used my DeadShot. Still, I'm a threat to bunnies at that range.

    Thanks for you support, DeadEye 🙂

    You should look into a portable bench for accuracy testing. Off an unstable tripod that's not a bad group. I'm sure that with practice and a wind flag or two you could reduce that group size by half.

    I just wish that my gun was capable of hitting any target at all at 145 yards 😎

    Yes, of course John; I use a Caldwell Magnum DeadShot FieldPod (which gives benchrest-quality performance) for zeroing, ranging, and groups. I use my Primos Tall Trigger Stick tripod w/ the two-point rifle rest attachment for hunting, which is more practical for that purpose. Actually, my Trigger Stick rig is pretty stable; not rock-solid, motionless sight picture stable like the DeadShot, but pretty darn good for on-the-fly hunting.

    One of these days, I'll drag my DeadShot out to the range and reshoot the 145 yard group. I just shot this group impromptu while out hunting. I normally don't mix hunting and ranging, but I got bored. Actually, I wanted to see if I could realistically increase my game range. I was limiting my game shots to 100 yards, but it seemed a shame to waste three mil-dots and 45 yards!

    Richardo; yeah, I did not expect to even hit the target at that range. But, then again, I never shot off of such a high-end paradigm.

    Sonny; I won't get many game shots at that range, but I wanted to see if Chairgun was good out to the limits of my optics. The more I use Chairgun (and get more proficient in measuring the required metrics for input), the more impressed I am with its capability. I rely on it implicitly in the field, and I am never disappointed. It is the best ballistics software for airguns, IMHO. I also have Strelok-Pro, which is amazing for long-range shooting with PBs, but it really is not the best fit for airguns, again IMHO.

    John:

    You were close! I dragged my DeadShot out to the long-distance range today and re-shot the 145 yards. Even though it was quite a bit more windy than with the Trigger Stick, I tightened-up the group from 5.5" to 3"!

    Just for shoots 'n ladders, I also shot a 75 yd group with the DeadShot:

    AnimalHitman,

    I share your fascination with "science" — just punch in the right numbers, and booom, we get right hits on paper and quarry.

    I'd be interested how you compare Strelok Pro and ChairGun, what is it you like better with ChairGun? (I assume you are talking about the mobile version of ChairGun to be fair).

    Jungle:

    I do not use the mobile app. I print out a range card. When hunting, I don't have time to mess with an app. I find Chairgun print-outs to be spot-on for my AGs. I find Strelok-Pro to be too cumbersome for for that purpose. However, I would use Strelok for long-distance PBs. It is far more comprehensive and detailed than Chairgun. But IMO, Chairgun is better suited for the short-range, sub-sonic, diabolo projectile profile of AGs.

    Sonny, yeah I finally have my Pulsar dialed-in!
