"...we trimmed them ,resized them and reloaded them ,but no dice,,,what gives ..."
First, all size dies and shell holders are made to bring all resized brass back to SAAMI specs we can swap reloaded ammo between rifles, It works fine IF the cases are indeed fully resized. Many people DO NOT SIZE CORRECTLY!
Following directions to "touch the shell holder and then turn the die down another 1/16. 1/8, 1/4, etc., turn are almost meaningless in application. Every press in the market has some measure of spring under sizing pressure, and to some degree even between the same model and brand. Thus, it is important that the size die be set to work with the press you are using, not your buddy's.
Simply push a fired case fully into the sizing die. Then, with the lever down and the press under full load, see if there is a visible gap between the shell holder and die. If there is, and there usually is, lower the ram, screw the die down a tad and do it again. Keep setting the die down until the gap disappears under full pressure. Then YOUR brass will be sized to SAAMI specs on YOUR EQUIPMENT.
I do NOT recommend doing this with cases intended to be used in a single arm, doing so works the cases more than is needed. Sizing each set of cases so that the bolt closes with just a hint of resistance for a specific rifle is a much better method of working. It will make for better case life but, those cases won't necessarily fit in other rifles.
