Hmm 257WBY....
How about a 280AI in a M24?
What really draws me to the 7mm-08 is that this gun will become my companion and will be using on smaller stuff like coyote as a varmint gun. Those 100gr varminteers would be fun.
What would keep me from going to something in a Mag is I will probably put well over 500 a year though this and worry about barrel wear.
So to me the 7mm-08, 7X57, 284, and if available 280AI are probably a the top of the list..
What about optics?
Not a die hard leupold guy but wouldn't a VX-III 2.5-8 with a B&C be pretty king with this gun?
