[QUOTE="palerider3, post: 1716448, member: 82117"] I do it all at 100 with a chronograph. Then after I have the load done I verify it at 1000 and then the range it starts to go transonic in I can, otherwise I just shoot at my 1530 target. I do load development starting with a ladder through a magnetospeed. I don't even try to group them, I just get the scope close while I'm burning these rounds. Once I find the node I want I load a couple 4 round sets at the seating depths I'm expecting to work and shoot groups at 100. Shooting at 100 reduces any exterior ballistic variances and gives me a true indication of what I am getting accuracy wise. Then I shoot a group at 1k, and a group farther than that. Verify drops and I'm set. Almost always have a load verified and ready to hunt in 40 rounds, sometimes less. I did load development a month ago for 230 ATIPs in my 300 wm and had a .4" load with an SD of 6 and ES of 17 in 28 rounds. Then shot 20 more just playing around and still have over 50 to hunt and play with. [/QUOTE]
