Can it be done? Building a wildcat that is a 6.5 Sherman. Am wandering if u can use the chamber reamer to open up a 280 AI seater die to use for my 6.5 Sherman? Using a .264 mag neck die to form the false shoulder and then fire forming. Resize the necks and ready to load. Just not sure what to use to seat with. Was gonna use a .264 mag seater but am thinking the that the .270 parent case would move around too much in the larger die and not give me a straight bullet seat. Going to have a custom set made but was wandering if this can be done for now while its taking 3-4 months to build the dies.
Thanks Roy
