I have limited expereince with this topic, other than having loaded the Partition in .338. I have some for the .270 but have not loaded them as of yet. I also loaded the Accubond in .338 and really liked that bullet. It was the best accuracy of the Three I loaded. Barnes XLC, Nosler partition, and Nosler Accubond. I have to agree with the comment that the next 5-10 years will yeild some great advances in bullet technology. Should be fun!
