Razmuz--
Those who have advised you to pull the bullets and start over have given you good advise. Pull the bullets, save the powder, reload the cases with the correct weight of powder FOR YOUR RIFLE, and reload the bullets. I routinely pull bullets using a kinetic-type bullet puller without damage to the bullets. Sometimes the bullet point (on spire point bullets) might get damage, so I just shoot those for practice.
Good luck!
