Gaoler 83 Posted August 24, 2011 Report Share Posted August 24, 2011 Hello All, I have today bought a Hawke 3-9x50 HD scope with a mildot recticle, I have zeroed at 30 yards as i always do (.22) , If centre is at 30 yards what are the other mildots measured at? Is it 35,40 then 45 yards (high) and then 25,20 and 15 yards (lower)? Any advice welcome Thanks John... Quote Link to post
tegater 789 Posted August 24, 2011 Report Share Posted August 24, 2011 I can give you a load of advice re how the mildot scope works, but my knowledge is using it with centrefire. I am guessing from the initial question that there is a field expedient for use with an airgun. If you need further or get no replies from airgun users I will re contact Quote Link to post
secretagentmole 1,701 Posted August 24, 2011 Report Share Posted August 24, 2011 Have you a Chrono? If you have get the foot pound energy of your gun, if not you need to borrow one, get the ft lb energy of your gun, then you need Hawke Chairgun! Doo not worry it is free, here is a link for you, http://www.deben.com/products/CGPRO.html Feed in the data, select the right reticle pattern and there you go, use it myself and it has made all the difference!

pianoman 3,587 Posted August 25, 2011 Report Share Posted August 25, 2011 Hello John. Chairgun programm is very accurate to work with once you get the hang of it. But it still needs you out in the field to shoot your rifle and see what it's truly doing over your hunting ranges. Accurate calibration of your scope's mildots is not that difficult. Just needs a bit of patient work in the field. I'd suggest you try using a 25 METRES (more accurate to work with than yards) zero as a datum and then set targets at 10 to 50 metres measured with an accurate tape. When you have 25 metres perfect centre-centre zero, wind down your mag to it's lowest setting 3xmag. Then shoot at 25 metres again. You may find that this has caused your shots to deviate slightly off. That's caused by a bit of parallax error that your scope is not correcting for and magnified by the scope's high mag setting you originally zeroed on. Keep your view down the tube as perfectly centred as you can. Adjust your 25metre zero and then fire at the 30 metre target on your 1st dot below bisected centre cross. If the pellet hits the 30 metre bullseye bang on, you have 3x as your perfect mag setting to build calibration on. If not, wind up gradually 3 to 3.5x to 4x, 4.5 to 5x and so on till you can hit 25 and 30 metres equally clean without any further adjustment of your mag ring or elevation turret. Your riflescope is now calibrated to your preferred optimum hunting range by it's optimum magnification . Then you can set to work on the remaining ranges and see where your shots are hitting on your optimum mag setting. Hope this helps get you shooting accurately over your hunting ranges.
