[QUOTE="pineywoods, post: 1221539, member: 48843"] Well here's a twist. I had 3 once fired brass (same headspace as factory) & ran them through the FL body die & got some sizing whereas the die wouldn't touch the factory Norma cases. According to my comparator, the headspace didn't change after sizing- however they chamber with NO difficulty whatsoever. I pulled the firing pin to get a better feel. I'm totally confused now... The dimensions of the body are .001 smaller on the new brass compared to the sized once fired as one would expect- the only difference that I THINK I see (no way to accurately measure) is where the body meets the shoulder. It looks pushed back on the sized case (which fits great) but the datum line is the same. These 3 cases were tight before & after being fired in the rifle...sizing them corrected the problem. New brass I'm working with is too small for the die to size at all ????....but factory Norma brass should chamber in any SAAME spec rifle....right ? Could damage from a cleaning rod affect chambering ? I know I'm grabbing straws ! Would a small base die work on my initial sizing ? [/QUOTE]
