The 30-06 CARTRIDGE is larger, and has more power than the 30-30. The size of the rifles that fire it can vary a great deal. Both fire a .30 caliber bullet, but of different lengths and weights. The cartridge case of the 30-06 in much larger.
No because 3300 is bigger than 3030
.223
it might be for the Krag rifle, cal. 30/40..... not 30/06
No
Talk to a gunsmith. There is more than one way.
Is 3030 greater or less than 3300

No. Both use the same diameter projectiles.
No. A 12.7 mm round is actually the same as a 50 cal, but just in a different sign. Its a gigantic round.
No. The .243 is a larger calibre, and the parent case is the .308 Winchester, necked down to accept the smaller projectile. It's considerably more powerful than the .223.
Size of the rifle will vary, depending on make/ model. The 30-30 BULLET is larger in diameter and weight than the .243, but has less energy. This is due to a slower bullet.
