Drogue shear pins eliminated. Main shear pin holes reinforced with copper shim stock. Hole in nosecone taped to reduce volume to pressurize. Beeper eliminated because unable to initialize after multiple attempts. Some weather-cocking, probably due to relatively low speed off-the-rail. Straight flight. Both drogue charges fired on schedule; separation occurred, but drogue did not deploy because it was anchored too close to the body tube. Both main charges fired on schedule; main chute deployed perfectly. No damage.
