Check your decimals - I think you mean 0.3 grain increments.
FWIW there is no reason to keep going until you see pressure signs. If you see a good node taking shape and the velocity is acceptable, you can continue refining the load at that charge weight and enjoy more safety and longer barrel life.

Agree with this. Lacking the fundamental knowledge and experience at this point it might be unwise to push any limits and rely in reading pressure signs that he may not recognize. I’d probably start with the first accomplishment of creating a safe, minimum charge book load with stated components. Let the experience build from there.
It’s so easy to get distracted as a beginner by reading about all of the different methods of load development and special tools and techniques for accurizing.
