Stinger, the criteria is, "We need something that works."
So you test and find out what works better than the other options. You then scream, "Eureka!" The next step is standardization and mass production.
It's pretty much the same for whatever purpose one decides upon. Try it; if it works, it's good.
From trying it, I know that an 00 Buck and five grains of pistol powder makes the '06 a good squirrel load. An 80-grain bullet ahead of a bunch of 3031 does horrible things to jackrabbits and buzzards. (Clue: Do not do this to a buzzard which is directly overhead. It gives a whole new meaning to "rain".) A 110-grain bullet is a good varmint load, and likely would be somewhat disruptive inside a Hostile Person. The 150 will take care of most any Bambi you'll ever see. IMO the 165 is sorta betwixt and between the 150 and the 180. More recoil than the 150 and less penetration than the 180--based on "ding depth" on steel at my 500-yard range.
Above 180? You're getting into specialized uses. 220-grain if all you have is an '06 and Great Big Bears are on the agenda. 230-grain VLDs for long-range target.
Testing weird ideas can be fun, particularly at age 16. You can carefully drill out the nose of a 220-grain lead hollow-point gas check bullet with a 1/4-inch drill. You can carefull cut off the exposed lead of a .22 long rifle cartridge. You can insert the remains of the cartridge into the hole in the bullet. You can load the bullet with no more than 20 grains of 2400. You can shoot at a tree limb with great expectations.
Don't bother. The result is under-whelming.
