...or less...?????

If we didn't have any existing cartridges, any existing firearms 'platforms', and just had primers, powders, and the technology to make whatever cartridge cases, and bullets, we wanted, what would it take to cover 'all needs'...???
Here's a template of 'needs'....
Now, one could say that you don't REALLY need a 25 or 35 or 45 caliber family of cartridge, because having just the 20, 30, 40, and 50 calibers would provide everything needed.
Indeed, in terms of 'leverguns', I think that for hunting and farm/ranch use, I could do with only three cartridges....
At the lower end, 22 LR (Ruger 96/22 or Henry 22 would be my choice), and the higher end, 500 S&W (BHA 89). The 'middle ground' would be either a 32-20 (for the 'nostalgic' me), or 357 Mag (for the 'practical' me). With those three cartridges, I could cover everything from chipmunks to grizzly bear, and would not feel ill-equipped.
For two-legged predators and the rifle-class of firearms, of course one could need a semiautomatic, and the cartridge choices would differ due to design considerations, but there are 22 LR semiautos (Ruger 10/22) and 50 Beowulf semi autos (AR-15), that clearly would equal the ballistics of the 22 LR and 500 S&W. For the mid-range stuff covered by a 357 Mag levergun, semi autos in any number of other rounds would suffice.
Now we are up to SIX rifles to cover all needs - so we have to add handguns, of course....

There are 'pocket pistols', 'holster pistols', and 'hunting (non-concealable) pistols'....
Maybe 22 LR, 9mm, and 10mm, or something similar...???
Anyway, just some food for thought when it is raining outside and the range is closed, or the ammo supply low, and it is fun to sip some tea, or bourbon, and speculate.....
