I would not recommend dropping to a lighter projectile with worse BC if he is looking at ranges of 500-1000yards. Too much wind deflection.
While I am inclined to agree with you, if he desires to use IMR 4350, he most likely will have to go to a lighter bullet.
I never suggested a lighter bullet, just made him aware of his options. What he does is up to him.
