[QUOTE="Deleted member 71114, post: 1339330"] A while back we did a little work on this and came to the conclusion that there are variations in the end result due to burn rates, type of extrusion - kernel size, and case volume. Without getting to in depth the fps spread can be different from one powder to the next because of the kernel surface area then combined with the case volume of a certain load. There will be averages that folks can go off of but the bottom line is case volume and powder type in each individual set up has a different end result in which is more noticed in the ELR world. Repeatable load charge is the most common issue and challenge and one that most folks overlook because they believe that their system is dumping charges at the upmost accuracy when in reality it's not. Case prep and consistency in powder charges are two key players in low ES's Just passing along the info we have worked through. Cheers Jeff [/QUOTE]
