Congratulations on the draw and good luck. You have more than enough gun for those "little" moose down there.
. Moose die easily usually - they may take awhile tho.
Good shot placement is essential - in heavy escape cover and within 100 yards, I prefer a cns shot. With a double lunger - they can go up to 200 yards, usually less. In the terraine I've hunted, I have several times been within a step or two of the downed animal before finding it.
They will be in rut, and calling is fun when they come in. The meat may not be too good tho. BTDT. I'd prefer an antlerless moose in that time frame, but what you have is what you have .
Have a grand time. Post us some pics.
