good shot, buddy! wrote:Well, thanks very much to all who responded, it was appreciated !
Soooooo, guess its a choice between the .280 and the .308, tho' I'm not sure about the .280 @ 300+ yds. putting down a bull elk. But I'll try doing a web search for ballistics comparison between the two. Thanks again to all.
PS: Doc, it's been my experience that you're absolutely right, re:"good friends" and "really good friends"........just never seen it in writing before!

But, if you are gonna be shooting Bull Elk at 300+ yards then you may need a 7ultra mag or a 300ultra mag. These are excellent for drilling a hole 300-500 yards!

And it just so happens that Walmart is running a special! You can get a 7mag or a 300, with a 3X9X40mm scope and a sling for $329!!!
