first off, I already know better than to try it, but out of curiosity, a friend told me 7mm mag ammo would fire from a 280, is this true? I'm pretty sure 280 cal is equivalent to 7mms, but i think the 7mag casing is larger in diameter.
Also, going elk hunting in wyoming this year, I would like to be able to take a shot up to 300 yds if needed, as long as I can make a good confident shot at this range, is the 280 going to have enough power at 300 yds. to take down an elk? how much am I at a disadvantage with a single shot by not being able to take a second shot? being used to deer hunting i think one well placed shot would do it, what do you guys think?
