I've been shooting shooting Field Target hunter division with my .177 Air Arms S500 for almost a year now. She's about 18.5 FPE at the muzzle with the 10.34 gr JSB's
I have a 4-16x44 MTC Mamba Lite scope set at 12 power which is the maximum power for that class.
I shoot zero for 27 yds which roughly gives me a flat enough trajectory to call it flat from 20 to 34 yds. Not much over a pellets width of difference between those yardages.
Now we shoot metal knockdown targets between 10 and 55 yds. With killzones ranging between 3/8 inch to 1.5 inches.
I concentrate more on getting my range finding set up between the 10 to 20 yd range. At 10 and 11 yds I have a 1.5 mildot holdover.
at 12 and 13 yds its 1 mildot. At 14 yds .75 mildot, at 15 yds .5 mildot, at 17 yds .25 mildot, at 20 yds close enough to call it flat on out to 34 yds.
I spend more time in this area because the majority of the targets will be inside 35 yds and I want to concentrate on not missing them if I can help it?
As long as I can hit that 3/8 inch killzone out to 25 yds I'm happy. The hardest part is setting your scope wheel up with the proper hold overs marked on it.
40 yds is about a 1/2 mildot and 45 yds about one mildot , but usually when you get out to those distances you are dealing with a bigger killzone. I've found that sometimes the kill zone is big enough at the farther distances I can put the cross hairs near the top of the kill zone and the half mildot will be near the enter of the kill zone and it gives you a little more leeway in making the shot. It's harder to range find with 12 power once you get past 30 yds.
At 50 and 55 yds it's close enough to cal it 1.5 mildot hold over between those two ranges.
So 10 yds is 1.5 midot, and 55 yds is 1.5 mildot with the 27 yds being about center way between the 2 extremes. And the 27 yard mark is closer to the apex of the arc of the pellet with my set up.
Hope I haven't totally confused you! LOL I understand it and it works for me so far!
Now my Cricket ,FX, and Dragon, I just zero them at 30 yds and the hold overs are way different but not as critical since I'm not shooting Field target with them.
