Thread: The Importance of Using the Right Data

Harvey in his 5th edition quotes 65 grains oh H4831 as a max for the 129 in the .264WM, the same max for a 120. 2213 maxes are 70 and 63 grains for a 120 and 129 but this is the old 2213 and not H4831 or 2213SC. So not a good comparison.

Historically ADI data has been less reliable than Harvey’s. Harvey always distanced himself from the adi data which was generally very conservative. It has improved over time but Hogdon data is a good cross reference.

O’Connor used H4831 war surplus in his classic .270 loads of 58.5 for a 150 and 61+ for a 130....
