[QUOTE="Joe King, post: 679954, member: 47325"] This is how I work a new load, first just pick an arbitrary seating depth that's in the neighborhood of COAL I'll load up 5 charges increasing in 1/2 gr increments, with the heaviest charge being 1gr above book max. when I go test this batch of test loads with a clean barrel, I will fire the 1st of each charge at some arbitrary target and inspect each case for pressure signs, if I see a hint pressure with load #4 and definitely see pressure with load #5 then I will not fire the other 4 fro Load #5 and bull em down at home. The remaining 4 of each charge will be fired round robing with a target for each load (search OCW load development) [URL="http://optimalchargeweight.embarqspace.com/"]OCW Overview - Dan Newberry's OCW Load Development System[/URL] next step will be to try a number of different primers, I like to used 5 different primers with 5 rnds each at least one primer will show you significantly tighter grouping than the rest, fired round robin style again Next is time to start looking for that seating depth your rifle likes, you can go from 0.00" off the lands to to 0.250 if you like for example, and just follow the crumb trail refining your seating depth until you get it nailed down. If you do it right you'll end up with a load that is both accurate and forgiving for temp changes. Just remember to shoot everything round robin, I like to wait 5-10min between shots to somewhat simulate a 1st round cold bore shot each time. [/QUOTE]
