If you have RCBS 44 mag or spl dies you can, with just a little skill, grind some of the bottom of the seating/crimping die off and use them to reload all three. OR just buy a seating/crimping die for 44 Russian. I've converted .30-06 to .308 amoung others. I currently use a .45 acp seating/crimping die for .45 Colt. I learned to reload along ago when die selection for some calibers was tough to find and was short of money too.
