I've been wanting to try this Creedmoor conversion for quite some time. Converting a common MILSPEC Lake City 762 cartridge to a less common 6.5mm Creedmoor. With the right tools and a little patience the 6.5mm Creedmoor conversion is quite easy. I dusted off my Redding T-7 and installed a 7mm-08 Rem trim die, a 6.5mm Creedmoor trim die with attached Dillon RT1500 trimmer, and a Redding 6.5mm Creedmoor FL Resizing die.
Initially I was unsure if I would need the 7mm-08 Rem die to step the brass down in preparation to set the shoulder of the Creedmoor cartridge. Ultimately it is not needed, but does make the process a bit easier, especially if your bench is not sturdy, or your press is not securely fastened to the bench....or if you're not physically able to apply the required amount of pressure to go from a .308 Win to a 6.5 CM in one pass.
Before I go into the steps. All of the brass used was true once fired, MILSPEC, Lake City headstamp, 7.62x51, and I did not anneal the brass beforehand. After doing these conversions I did a few more using some of our annealed Lake City 308 brass. Working with our ready to load brass was far easier as the body of the case had already been resized and the neck and shoulder area was softer due to annealing.
