Buying equipment to load up one caliber, one time would not be cost effective. As long as you plan on loading regularly for other calibers, you can save considerable money (and have the satisfaction of "rolling your own").
Because you will not be shooting and testing the ammo, stay away from the max loads in the books. Max loads may not be safe in your gun and probably will not be as accurate as possible. My rule of thumb is drop below the book max by 1-2 grains on the powder and the load will be pretty darn accurate. I keep a few boxes of assorted ammo for SHTF situations in case I "find" a weapon in that caliber. I have dies for 6 calibers that I do not even shoot. If I scrounge brass from the range, I collect it up and when I have enough, I load it up.
In life, strive to take the high road....It offers a better field of fire.
