Nosler lists 41grs and Sierra lists 41.8grs with their respective bullets, so you are definitely under the minimums for both bullets. I personally have never messed much with the starting charges, and on the occasion that I did, it wasn't as slow as the manual suggested. Then again, the top velocity wasn't what they had listed either!
