[QUOTE="Dr. Vette, post: 1492671, member: 22335"] For my 7mm Wby with the 131 Hammer Hunter, I tested Norma MRP from 74.0 to 78.0 grains, loading every 0.5 grains. Based on those speeds (1 shot each) I went back and tested 77.0, 77.5 and 78.0 grains. The 78.0 grain group was 0.84 inches for 4 shots at 100 yards compared to 0.87 and 1.10 for the 77.0 and 77.5 grain 3-shot groups. My bullets are seated so that the loads will fit into the factory magazine well with no issues. Final speed average 3550 (3545-3553). I loaded up a bunch at 78.0 grains, sighted in the rifle, ordered my turret tape from Custom Turrets, and went hunting. I didn't have any more time than you did. All of this was done with brass I bought from someone else, cleaned, annealed and sized. The rifle is new to me so I didn't have any that was formed to this chamber. By firing some factory ammo in this rifle as a test for shoulder length I body-sized my brass to the correct length, and all is well. Good luck on your hunt! [/QUOTE]
