Loading 22-250 cases with 37.8 grains of H380 and Hornady 55gr SP bullets. Accidentally used Winchester Large Rifle for Magnum primers. The book shows load options of: 35.0, 36.4, 37.8, 39.2 and max of 40.6. I used the middle of 37.8. Do I need to pull apart 200 rounds and start over with non-magnum primers?
