Joe has a personal vendetta against Trump and wants to prove he can cheat his way to victory again, so his stubbornness will keep him on the ballot, unless of course the above scenario does become reality.
Custom drag model is the way to go but truing the BC for the distance your shooting is actually what the bullet is doing during flight vs making up a velocity number to coincide with your elevation adjustment.
It's a 24" barrel so I'm hoping to try them and get 2700-2750. I have N570, N565, N568 and H1K to try, however I'm concerned once the weather gets cold that the SG will dip to 1.4 or less.
Usually everyone's first choice for a magnum cartridge regardless of distance, but yes they perform exceptionally well at long range. Just very hard to come by.
Also, I don't know how long you're waiting between shots, but that barrel has to be heating up quite a bit during a 15 rd group, burning that much powder, which will affect the ES.
