[QUOTE="J E Custom, post: 401789, member: 2736"] This condition is common for several reasons= One could be the measuring process it's self. Measure the same piece of brass at least 4 or 5 times zeroing the instrument each time and wright down each reading, obviously if they are identical then this is not the problem. Mose brass has slightly differences in hardness and thickness so the amount of spring back will vary plus the loads them selves are not exactly the same pressures and this can cause the brass to measure differently. Head space could cause this if it were poor allowing the brass to move differently under certain conditions. If the chamber is not clean and dry (No Oil) it can allow the round to move differently each time it is fired. I'm sure there are other reasons that this can happen and maybe the others can add to this. J E CUSTOM [/QUOTE]
