FL Resized 6.5x55 Not Chambering??

[BlackPowderBurner]

I was just experiencing the same thing with a 6.5x55.
I recently got a new to me CG63 target rifle built by Norma, and it has a much tighter than military spec. chamber and shorter throat. No need to shoot the 156gr. round nose I guess.
I was making up a dummy round to try in the CG63 with a PPU case fired in one of military rifles, and no way would it chamber. I trimmed, lubed, screwed down the die, still no way. This was an RCBS die. I also have a Lee, but I didn't try it.
I finally gave up and tried one of the once fired Norma cases I ordered with the rifle from TradEx, and it chambered with no resistance using the same RCBS die, so thankfully the Norma brass must have been fired in a tighter spec. target chamber.
I'll try the Lee die out of curiosity.

Since you just so happen to be in Winnipeg, here's an idea: if you can't get your ppu brass to chamber, how about we swap brass and see if it'll chamber in different rifles? Your chamber might be tighter than mine or looser, one of us might come out ahead and neither behind!
