    Scope zero range

    I set my scope for a 25 yard far zero as that seems to be the range that I use most of the time. Near zero is approximately 12/13 yards for my HW95 .22 using H&N FTT 14.66 pellets.

    To one shot one kill, you need to seek the S. Kill only comes from Skill

    Learning the holdover and under for your particular scope at the magnification you use will be far more use than the zero but an average between the two will usually work best.

    I suggest you invest in a ballistics program/app

    Good advice from angrybear about getting a ballistics calculator app.

    To give an example my Falcon .177 zeroed at 29 yards, on 7x magnification gives a near zero at 13 yards.

    At 20 yards it needs about a quarter mil hold under.

    Hold over of half, one, and one and a half mil dots work out at 37, 44, and 51 yards.

    Of course scope height, pellet weight, and velocity are the variable factors for your particular set up.

    get chairgun and play...

    I always went for 32 yards as it gave a loverly PBR of 13-34 yards where the pellet would land within 1/4" of my aimpoint. Job done.

    Unfortunately Hawke stopped supporting Chairgun at the end of 2018, so I'm not sure if it can still be downloaded, it's not on their updated site.

    looks to still be here, down the bottom of the page, under legacy version downloads:

    there we go, 30 seconds with chairgun, 32 yard zero, KZ = 0.5" (so within 1/4" either way):

    Lovely little chart there, JB, giving so much very useful information. Just goes to show, a picture is worth a thousand words.......

    Sub 12 springer, using "average" weight domed pellets, I usually set them up for 25 yards in .22 and 33-35 yards in .177.

    Pellet BC ?

    How do you find the BC of a pellet, example, H&N FTT 14.66 gr .22 Caliber Pellets. I don't find any BC info on the tin. Thanks

    I found this site with the info. https://nnh-net.com/bc/ Again thanks

    I haven't checked recently but H&N show BC figures on their site, I think.
    Also, hardairmagazine have an extensive listing of various pellets in different calibres.

    However (and I'm far from an expert), these figures will be approximates. The BC for any different pellet will vary from gun to gun and the only accurate way to get a precise value for your own rifle / pellet combination is to test and measure velocity at different ranges thus enabling calculation of the BC thereafter.

    The existing charts do make for interesting comparisons, though, and I applaud the efforts of those who took the time and trouble to put the work in.

    P.S....That's a useful listing provided on the link, Travis.

    Chairgun includes the BC of the pellets that were available at the time for their list.
