Not a big 7mm fan but I've seen it work on moose many times ....
My old mans favorite though, he has put a boatload of moose to sleep with one in the last 30 years, last fall I had a chance to take my dad on a moose hunt to my happy hunting grounds and he put his 7mm RM to work on a nice bull with the 160 gr Fail Safe bullet .....
good times........
