Hoping to go on a moose hunt this fall and thought I'd escape from the weather by looking at what rifle to bring. Got on Federal's website to compare the 7 mag with the 35 Whelen. At 2-300 yds the 7mag 175 grain bear claw and the Whelen's 225 grain bear claw are pretty close in energy. The 7 mag 160 grain partition seems to have even more energy. Would the heavier bullet be a better choice and how is it the 160 grain has more energy at 3-400 yds than the 175 grain.
