[QUOTE="Pdvdh, post: 1395313, member: 4191"] Researched case capacities. The 7mm RM has slightly greater capacity - about 2 grains more H20. This, and the larger bore diameter of the 7mm RM means that the RL26 powder charge Alliant shows for the 7mm RM would generate higher pressures when used in the 264 WM. So this reinforces my earlier post. You're already loading at the max powder charge for the 7mm RM with 140gr bullets. So you're exceeding those 7mm RM load pressures when using that powder charge in your 264 WM. Whether or not it's a safe pressure in your rifle is something you're in the best position to determine. I don't own or use Quickload. Take care... [/QUOTE]
