[QUOTE="JungleShooter, post: 2276108, member: 110729"] I'm sure for closer ranges absolute precision is not a big factor. But when minute precision counts for way out there shots, well... So, you'll excuse me to bring this up: Despite the "ridiculously" short ranges of airguns the demands on their precision are huge: ▪one inch and two inch kill zones ▪elevation adjustments of over 10 mil or more to reach mere 150 yards ▪ranging error of 2 yards can move your shot already outside the kill zone (@ 70y) ▪a light 5mph wind moves the shot outside the kill zone — at a range of only 45y 😊 All that to say, the most precise method I know of is to measure the distance from point of aim to point of impact pretty much at the barrel (if your scope only parallaxes down to 100y, that method won't work, sorry). The instructions are fairly straight forward, right here: [URL unfurl="true"]https://airgunaccuracy.wordpress.com/chairgun-and-scope-height/[/URL] Matthias [/QUOTE]
