Hi terrom,
As Mooly said, either value will work perfectly fine.
If you want to prove it to yourself, calculate the percentage error from 0.3000000 ohms. You will see that these values are more than close enough. They will be within the tolerance of the resistors you eventually buy. So don't worry about the numbers. Besides, the resistors you get might actually be pretty close to 0.3 ohms if you buy 0.33 ohms. Many times resistors measure low, just like electrolytic capacitors.

if you buy a 0r33 it will have a tolerance. +-10% allows it to be from 0r297 to 0r363.
you could adjust the final value by adding a 10r in parallel with the 0r33
0r33||10r = 0r319
0r33||10r||10r = 0r310
0r33||10r||10r||10r = 0r300
The 10r adjusters can be cheap, metal film, 1%, 600mW, 50ppm/C, or 100ppm/C
