[QUOTE="Driller, post: 2337516, member: 25897"] [ATTACH=CONFIG]33665[/ATTACH] I work rifle loads up by 0.5 grains through the range in published data. When I find a good accuracy node, I'll work up some more by moving a tenth of a grain or two up and down. To keep from having to record all of the groups and keep the pace of shooting up, I take foam plates and put a target dot on them to use as targets. I'll shoot my range of loads, record the group number and chronograph data in a book, and then label and save the plates so that I can measure the groups and analyze them later at the shop. The plates will fit in a gallon baggie and you can look at the actual group instead of reproduced picture in your range book. If a pull a shot or have some other mistake, I'll note it in the book for when I look at the plates later. I've started putting three or four dots on a plate to keep from using so many. You can get a big package of foam plates at Sams for next to nothing and the target dots are like 5.00 for a hundred or so. You can also make the dots with a marker, but the paste-ons are easier to see at 100 or 200 yards. Once I find a load I like, I'll stretch out the range to see how they do. [/QUOTE]
