Hi Kurt-----------thanks for the reply---------------dimensionally everything is as it should be, length within 0.01 of target length 0.004 short of the end of the chamber, finger tight seating just as originally set up--no crimp----wiping between shots------this lot of ammunition was "blueprinted" as a lot of 250 rounds just to make sure errors would be "shooter" and not ammunition if things went someplace they wern't directed to
i'll be digging around for different paper of the correct thickness (0.0017) and see if i can find some thats a bit more moisture resistant----------------when i tried wet wrapping with this paper it was really limp and stretchy, that and the barber towel atmosphere are what i "think" is going on.
The paper is stuff from hobby lobby --easy is get and the right size, "Masters Touch" and it was working and did work again when things dried out.
Again thanks for the reccomendations
Dave
