[QUOTE="65WSM, post: 2312581, member: 9551"] I have struggled with the .243 WSSM. I purchased three used Model 70s and had a gunsmith chamber a custom barrel to replace one of the factory barrels. I purchased full length sizing die from Forster. It would not size the cases enough to close in any of the chambers. I purchased a Redding Full length Bushing die and the same story. In despiration, I purchased a RCBS full length size die and it would not size cases to fit the chamber. In desperation, a friend tried a Redding full length size die in .300 Remington Ultra Mag. It was successful in sizing the base of the cartridge to fit the chamber. He used the Redding Ultra press. The .300 RUM die split under the pressure and I got a hundred cases to fit. Those cases would fit any of the chambers. My former friend would not risk the replacement die I purchased for any more cases. I had Whidden build a die to size cases and it works, but my RCBS Rock Chucker does not have enough leverage to close the die on the shell holder and I have to get someone else to size for me. My conclusion is that there is a disconnect between what the die makers and rifle makers believe are the specifications. [/QUOTE]
