Hi Rocky,
If it were any other member making that post I would have a little fun with it. I know that you really know your stuff and that your a gentleman as well. It's a pleasure posting on this site. Sorry anyway for taking so long to answer.
I pretty much agree that 400 yds is kind of far and I pass up shots even shorter than that here as I have the freezer full and would rather make a sure shot.
But many of us are human and if it's the last day most are going to wing away. The 7mm-08 is a neat round but is that the biggest gun you have out there in Utah?
I looked at some data and if you shot my 7mm-08 with 140 BTs zero'd at 250 it would be about 18" low at 400 yds and in 20 mph of wind drift a couple of feet. I don't think I would shoot either.
On that last day I think I will bring my 264 WM shooting 120's at 3350. It will be only 11" low at 400 yds and drift a lot less or a foot and a half to be more exact. I would shoot with the 264. Thats what it's for.
