Look again at the 308 Win round. You can find lever guns made by Browning, Savage, & Winchester, all for less $$$ than the Ruger #1.
1) Buy a set of carbide 30 carbine dies for neck sizing.
2) With once fired brass, full length size, trim to minimum trim length, & load.
3) Neck size after that 'till the brass reaches it's max case length.
If loaded moderately, you'll get many loads before full length sizing is needed again.
The plus side of 308 W. is; avalibility of afordable components (you can shoot the 308 W. till the brass needs FL size the 2nd time, throw away & buy new cheaper than buying one of the less common calibers mentioned. 308 W. will have good rifle ballistics for longer range shots.
As for a handgun to match, settle for a 30 carbine, you already will have dies for it
