Rug,
I have not used the 6,5 on moose myself. I have, however since 2003, danish hunters come hunt wildboar with me.
Many come with their 6,5x55, after all, it kills moose.
Long story short - the fame of the 6,5x55 comes from its inability to throw the heavy 10 gram (160 gr.) hard enough for the bullet to fail tensily.
Hit the soft stuff (tissue, ribs, heart, lungs) and your animal will be dead.
Hit hard stuff (bones, heavy muscle, shield on a boar) and you are in trouble.
I have followed up to many boars wounded with the 6,5x to condone its use with the regular bullets for boar. I would feel the same for moose.
Game changes dramatically with todays bullets, though.
Think 130 gr. TSX.
