[QUOTE="BrentM, post: 2327851, member: 61747"] Satterlee ladder is all I do anymore. I shoot 1 at .5 grain to ident potential node and max charge. I come back and shoot .2 around the upper node in no more than 3 shots. Usually that tunes/idents a node quite well. I will confirm that node with another 3-5 shots. I have had success with a brand new development around a bullet in as little as 15 rounds if I have my guesstimations down right. If starting from scratch with a new powder I will back off book max 2 grains and work up. So if max is 60 grains, ill start at 58. So 58, 58.5, 59, 59.5, 60, 60.5. 6 shots. Let's say 59 to 60 (60 no pressure, 60.5 shows signs) show lower es and 59.5-60 is lower than 59-59.5. I will run 59.3 to 60 in .2. So 59.3, 59.5, 59.7, 60. Let's go with 3 each. (you can do 2 if you are confident in your data reading skills). 12 shots. Let's say 59.5-59.7 are showing low sd and es. You can load 3-5 of each. 6-10 rounds. Or you can do 59.5, 59.6, 59.7.... 3 of each. I'd likely just do 59.5 and 59.7 for a 5 shot confirmation of sd and accuracy. 28-30 rounds and done. This is pretty much what Satterlee does. [/QUOTE]
