[QUOTE="Don A Parsons, post: 1724108, member: 97414"] We do 3 simple ladder test up here in the North for F Class. 7 to 9 varying loads to shoot at the dots at 100 meters... 3 cartridges for each of the 7 to 9 varying loads... To lesson the variance between the targets we shoot the lowest charge and work our way across the target dots at 100 meters using the 0.3gr powder charge... Once we find the tightest vertical at that distance we move out to the 600 metre... Now we have about 4 or 5 loads to test using 3 cartridges per load... We set up the big chunk of card board to find the tightest vertical at that distance... Now we're down to 2 or 3 test loads,,, same idea of shooting at a clay bank at 1000 meters... If our calculations are correct from 100 and 600 meters,,, they should be on par at 1000... We only shoot our ladder tests on calm days late in the evening... Simple easy and fast... Of course we have a mobile reloading set-up that we bring to the range,,, the control center saves alot of time since we can change loads on the fly... 1 to 2 hours to find loads for all rifles that come out to the range... We test these loads over a period of days to make sure that they are a go... Different temps and elevations along with low to high humidity days... Cheers from the North [/QUOTE]
