[QUOTE="MNbogboy, post: 1730132, member: 18849"] Here's my take, the ruger chamber is "fatter" (but not necessarily longer). The die/shell holder setup even at cam/over is lengthening the cases longer than the savage and ruger chambers. Problem is the PPU brass soft enough to "flow" well in the die and is not springing back enough (like other brass you have tried). The feeler gauge between the shell holder and case head trick may show that the above is true. But if you are already hard camming over it may not. Proper annealing and the pause may help. If all else fails you can remove material off the top of shell holder or bottom of the die. Also use a Sharpie to color a case to detect where the actual interference is. If it is in the body a small base die is the cure and not related to length at all. If interference is at the body shoulder junction be careful not to bump back too much or brass life will be shortened due to head separation. I've found ppu brass is ok after careful sorting (weight/volume) but about 50% loss for culls. Makes it more expensive. It anneal well. Pockets ok after 8-9 loading with mild loads. Lighter or equivalent to hornady with approximate same case capacities. Bad thing not made in usa. Btw; I convert 8x57 mauser brass for my 6.5/257 Roberts Ackley 40deg. If lapua made 8x57 I'd prob use that. Good luck, Randy [/QUOTE]
