I've been wanting to put my 0.02 in for a while. I've seen plenty of shows on OLN, Mens Channels, and Outdoor network where they have taken Moose and other large animals with the .270. Granted these people were guided in and they were close range shots with the .270 when they took their Moose.
I've hunted with the .270 and I love this rifle cartridge, in fact I took a very nice cow elk at 250 yds with federal 150gn cartridge with one shot. I think that we see too much of the hunting shows where the hunter shoots the animal in the neck or spine and it dumps the animal on the spot. I think this is done for dramatic effect, but that is my opinion again.
I personally have never hunted moose but I want to, so much so I had a .338-06 built just for the occasion. I'm just waiting to win a draw, so it might be a couple of more years yet. Had I drawn an year ago I would have hunted with my .270 because that is the largest caliber rifle I had at that time. Again the Shiras moose is defiantly not the largest in the species and the .270 would have worked great.
I just have a problem with people suggesting a 7mm, .300, or .338 magnum rifle to young shooters. These are great cartridges, but most young hunters can't handle the recoil to shoot effectively. I applaud those of you who recommended the .30-06 to this young man because it is a rifle he can grow with until he is ready for the magnums.
I just wish that some of these threads wouldn't degrade into p---ing contest over whose is bigger. I also know some of the readers of my post will be saying that I'm a hypocrite for having the .338-06. My reason for that rifle was that I wanted something that not everyone owned, and because I hand load I could build the cartridge to its full potential.
