Finally a video that explains how to tweak the ballistic calculator in digital scopes. I'm tired of endless videos reading the specifications without any explanations. Great job! Thank you for this one!
Fantastic indepth tutorial. I've recently purchased my first digital scope with BC (DNT ZULUS 312) I think this video will be invaluable setting it up as I've never used one before. Many thanks and best wishes from Northern Ireland 👍
Best video on this subject matter out there. Simply explained. Great diagrams and instruction. Thankyou for the time and effort it took you. Very appreciated ❤
Thanks for sharing and spending the time to do this video, I am sure it will help those of us trying to set up our ballistic calculator in our scopes and not become frustrated with it when trying to tweak it in set up ,or wonder why it doesn’t work at different ranges . I was just trying to set mine up last weekend and now have more information about how to set it up easier thanks again looking forward to seeing more of your videos cheers 🤠🇦🇺👍
Hi Spiked, your welcome. Ballistic calculators can be quite frustrating when they don't do what you want them to, but when you get it right it is very satisfying to hit what you are aiming for every time. Let me know how you get on.
Like every one says, this is a excellent, clearly, well thought simple to understand video. Thanks for your time in explaining every aspect of using the BC on these scopes, you now have a new subscriber through this video.👌👍
@@PrecisionPellet just set the scope up this afternoon, was very easy thanks to this video. Spot on from 4m out to the furthest I could get today which was 57m . Thanks for everything
Very well done. 👍🏻 I’m getting started with my first digital scope on an air rifle. I’m going to start the zero process again using your recommended distances for fps above 900 and then follow your steps exactly. Thank you!!
@@PrecisionPellet I spent some time working on this today while I had a halfway decent day (it's been cold and windy here in upstate New York). I re-zeroed my air rifle to 40 yards based on the average FPS of 930 I get on my chrony. The holdover was spot on at 10 yards, and now I've been testing it out at 20 yards. I had to raise the scope height in the BC from 3.75" to 4.0" to get it back to being spot on. Does that sound normal to you? It started snowing and is supposed to be crappy the rest of this week, so as soon as I can I'll test it out at 30 yds. One question I have: when I'm finished with the 5 steps do I have to rezero the scope, or if I do rezero, do I need to go through the 5 steps again? Thank you!!
Hi Michael, 4 inches sounds quite high, but that will depend on your rifle and which rail/rings etc you are using. (AR style rifles seem to require high scope setups). I'm assuming you have measured from the centre line of the barrel to the centre of the scope tube, and its was 3.75" which is what you used as the initial height when setting up the Bal Cal, in which case tweeking it to 4" sounds quite reasonable. Once you have zeroed your scope and set up the bal cal, you shouldnt need to rezero again, unless you change one of the paramiters like pellet weight, velocity or your zero distance. If you find your zero has shifted slightly and you need to rezero just an inch or two, that will have no effect on the bal cal and everything should continue to work as it was before. Having said that, its always a good idea to recheck your zero, a close distance and a far distance every once in while, just for that piece of mind that everything is still where it should be. Once you understand the principles of how to "control" the Bal Cal to get it to do what you need it to do, you can make tweeks and changes when ever you feel they are necessary :-).
@@PrecisionPellet Thanks for the quick reply! Yes, I measured correctly and the physical center-to-center measurement is indeed 3.75" - what I had in my initial bal cal settings. I'm also using a 20 MOA mount with my scope and air rifle - I couldn't get it to zero without switching to the 20. So maybe that's why I needed to increase it to 4"? I'm actually at 4.30" now that I had an opportunity to get back out and test it at 30 yards. Thank you again - the video is very helpful!
Great video! Just getting started back into my favorite childhood hobby and curious as to which optic you have mounted for night vision. I recently purchased an FX Impact M4 in .30 cal. and I have come to respect your opinion on these things. Thank you.
@@PrecisionPellet Thanks! Question regarding the earlier video review of the OneLeaf Commander NV500. Excellent review. However, at the end you stated that you would be leaving it on your .25 cal. In this video, you've reverted back to the Pard on the .25 . Did you encounter issues with the OneLeaf? Your earlier video had me convinced to purchase the OneLeaf and now I'm a bit concerned. Thanks again.
Hi Sawyers, the OneLeaf Commander is a good scope, there is nothing wrong with it, and for its price it really does have a huge amount of features. It comes down to your budget. If your budget only goes as far as a Oneleaf, then thats the one to get, it can do everything that scopes twice the price can do. Its just big and heavy. But if your budget can afford a Pard or similar, then get one of those. They are just lighter and smaller than the One Leaf. If you have spent the money for an impact, I'd say a Pard NS4K or a Zulus (or something better) would be a good match for that rifle.
Hi Wizard, Yea that should be fine, as lonf as you dont make big changes like moving your zero from 20y to 50 y, But if it is just a slight re-zeroig it wont make any difference.
A great video with a lot of very useful practical information on getting the best out of a ballistic calculator. However, I disagree with you regarding the importance of projectile weight For sure, projectile weight is important when trying to correct for windage but it has virtually no effect on how far a pellet drops during the time of travel between the muzzle of the rifle and arriving at the target All objects fall at the same rate with only air resistance making light objects like feathers drop more slowly than heavy objects like lead balls. Air resistance along the path of the projectile is far, far more significant than air resistance at right angles to the path of the projectile Try using a ballistic calculator app and set up a ballistic profile for a given weight of pellet weight, muzzle velocity, zero distance, ballistic coefficient and scope height. The ballistic calculator will generate a table showing the projectile drop at different distances. Note the drop at a few distances and then go back into the ballistic calculator and change the projectile weight and then let the ballistic calculator create a new table based on the changed projectile weight. if you then look at the drops for the same distances as on the first table you'll see that they are the same or have changed by such a small amount as to be negligible
Hi Bruce, Thanks for your message. I enjoy constructive conversation, so I appreciate you reaching out. The first thing I'll say is, as I said in the video, I am not an expert on anything, and that video is not an official way to set up a ballistic calculator, its simply what I have found works for me. And the second thing I'll say is, we are allowed to disagree :-) You may well be right that a ballistic calculator app (like chair gun or the element ballistic app) only gives small changes in drop if you change the projectile weight, but: 1)- small changes at 50 yards with an air rifle projectile means the difference between a brain shot or a miss. 2)- I dont use ballistic apps when taking shots, I use the ballistic calculator thats built into the scope thats on the rifle I'm holding in my hands, and from my experience, they are "projectile weight sensitive". Just as making small changes to the scope height or the projectiles BC will change the predicted POA, changing the projectile weight will do the same. I tried what you suggested, took the calculated drops (from the element ballistic app) of my favourite go-to rabbit culling set up, an 8.44gr exact pellet doing 813fps, at 75y it is 10.6inches and at 100y it is 27.8inches. I then kept everything the same, and changed the pellet weight to an exact beast, 16,2gr, same caliber, same velocity, also zeroed at 35yards, drop at 75y is 6.8inches and 100y is 21.9inches. Thats a difference of 5.9inches/15cm at 100 yards, and 3.8inches/9.6cm at 75yards. Thats not a missed head shot, its not even a missed chest shot, its not even a wound shot, its a total clean miss on any small game. From 25 years of practical air gunning and hunting, competitive archery (out to 90meters), bow hunting, powder burner hunting and powder burner reloading, I have absolutely no doubt that projectile weight effects how fast the projectile drops, regardless of velocity, frontal surface air resistance, drag coefficients or anything else, weight matters ;-) But we are allowed to disagree :-)
@@PrecisionPelletThe weight of the pellet has no effect on how fast it drops but... time in the air does. The heavier pellet keeps its speed better than the lighter one and therefore, all else equals, the former spends less time in the air and drops less. That's why weight matters to the balistic calculator. Only in an empty place with no air, a feather and a much heavier object will drop at the same rate.

@brucemcpherson8832 Try throwing a 10 inch diameter lead sphere at 1000 ft/s and a 10 inch diameter foam or styrofoam sphere at the same speed and tell me that weight don't matters.
