I worked up 2 loads today out of my dads new tikka in 7 mag. I used the 150g btip and IMR-4350 powder. I tried 62g and 63g of powder, with a fed 215 mag primer, and an OAL of 3.260". I was a bit dissappointed with the velocity, but the accuracy of the 63g load made up for it. 62g produced a 1 inch group for 4 shots, with velocity being 2860fps. 63g game me a .45" 4 shot group with 2960fps. I was also amazed at the consistency of the velocity. The 4 shots were all with 10 ft second from highest to lowest. Very uniform velocities. I will load up the rest with obviously the 63g load and zero at 200 yards, then shoot some groups at 300 and 500, and my dad will be set up for long range deer.
