Here's the ORK of the rocket i'm planning to fly in a few weeks for my L1 cert. It is 4'' in diameter and 150cm long. However, I am slightly worried about the BP charge not being enough to push the nosecone out, and before you tell me to ground test, I live in the UK, where BP is illegal. The calculator shows that I need 1.7 grams of BP to push the nosecone out, but CTI Pro38 reloads only have 1.4g. What should I do?
