the 8mm rem mag is awesome! certainly a 400yd elk gun, and def more gun than a .338 win mag or .300 win mag I believe.

I believe it was kinda the first of the new ultra mag type 300-338's, though it failed, nto sure why, maybe cause it was named "8mm" that's one of those rounds I wished had made it.

Certainly a great round that may be worth owning/hunting with, not sure how available ammo is, if at all? sure rem prob still makes a round or two. I'd probably stick to 200gr or 220gr rounds.....and ya dont worry about an elk at 400yds,
