It seems to me that a 35 caliber selection - one a year. Start with a 357 mag, then a 35 Remington in a 141, and a Marlin 336, a 358 BLR next, a 35 Whelen (bolt this time) or 350 Rem Mag after that. Finally get a 358 Mag. This could also be a 375 Ruger necked down
For molds start with a 358 in a Keith Style - about 160 grain, then buy a new mold to go with each rifle.
Then after getting one of each, fill in the gaps with a second 357. This time get a single action or a double action depending on what you bought the first time. Then make sure you have bolt and pump actions in the rifle calibers. In the case of the biggest cartridges you'll need to substitute a single shot in place of the pump actions. Finally look at a SMLE bored out to a 35-303. A 35 Winchester would be nice. And did I mention a 357 lever action?
