Yes, the bullet is bigger in both diameter (.243 versus .223) and weight. The .243 can use bullets that weigh up to maybe 130 grains, which is a lot more than most .22-250 bullets weigh. But the .22-250 fires at a faster velocity, so it is sometimes the better choice for varmint hunting.
In ascending order: 225, 225, 243, 243, 259, 276, 293 In descending order: 293, 276, 259, 243, 243, 225, 225
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.
225 + 243 = 468 The increase from 225 to 468 is 108%
