2nd wind, good luck with your continued load development and testing I believe you'll like the results with the Hornady 200 RN. I found some Ken Waters data for this bullet last season, loaded over 54.0 gr. of IMR 3031 it produced 3 shot cloverleaf groups out of my rifle. I harvested a nice KY whitetail with this load, the bullet expanded perfectly and weighed 122gr. when recovered.
