[QUOTE="shinbone, post: 1744098, member: 15248"] I am always fine tuning my load development process. Currently, I find seating depth (which I call "jump" since it is also how far the bullet moves or "jumps" before hitting the lands) before doing any powder charge testing for a particular bullet. I shoot 2-shot groups to find a rough seating depth to then do the powder charge tests. Then, once optimum powder charge is found, I fine-tune the seating depth using 3-shot and 5-shot groups. Some example of seating depth test results: .300WSM [URL='https://randallcherry.smugmug.com/2019/Guns/i-BC92fjW/A'][IMG]https://photos.smugmug.com/2019/Guns/i-BC92fjW/0/eb249071/XL/Adjustments-XL.jpg[/IMG][/URL] .223 Rem [URL='https://randallcherry.smugmug.com/2019/Guns/i-LqQvLRn/A'][IMG]https://photos.smugmug.com/2019/Guns/i-LqQvLRn/0/b4310690/XL/Adjustments-XL.jpg[/IMG][/URL] [/QUOTE]
