[QUOTE="HammerB1, post: 1154915, member: 8224"] Thanks Randy, The 6mm rem brass I have is once fired and has already been resized, trimmed and neck turned for my 6mm rem. That being said, I have tried just resizing to 257 Roberts and after fireforming, primer is sticking halfway out of cartridge. Next, I neck sized up to 270 then back down to 257 to create a false shoulder then fireformed and same thing. Did I not get enough shoulder tension to take the impact of firing pin or is there something I'm doing wrong? I have fireformed many other cases doing this same procedure and has worked flawlessly. Also worried about overworking the neck. Brian [/QUOTE]
