So far this year, I have developed highly accurate loads for multiple calibers including 7X64, 7mm Mag, 300 Win Mag (in 3 rifles) and 8.59 Titan using Lapua Naturalis bullets. Now I am trying to "validate" my loads by loading the optimal charge in each caliber and testing again. Here are the 300 WM validation loads. The charge is 72 grain of N560 for all rounds. I have loaded 15 rounds using a new N560 powder can and 15 rounds from a previous powder can with a different manufacture date to see if change in lot number makes any difference. I hope not.. wink
