As others have stated, I don't think your choice of rifle is going to get you to 1500 yards. Look at it like this:
You want to drag race over a mile stretch and get there the fastest (Gun wise - Most accurate). Instead of a sports car (Bolt gun) you chose a pick-up (Modern Sporting Rifle semi auto). The pick-up (308 Win.) has the same cubic inch V8 motor (Bullet Weight) as the sports car (.300 Win Mag) but the sports car has more horse power (Higher velocity) and a higher Power to Weight ratio (Less drop/drift). The sports car has a tuned race suspension (Stiff 24" free floated barrel), the pick-up is tuned for rough terrain (mid-weight maybe free floated 20"). While the pick-up is just fine for what is was intended it is not the right choice for the application at hand. You could add some drag slick tires (High end optics) but it is not going to fundementally change the resulting outcome. The sports car will always get there first because it was designed to do that job at the expense of other tasks.
Back in the day, I shot M60 MGs out to 2,000 yards. I hit the target a couple times but it wasn't because I was a good shot. It was beacuse I expended A LOT of Uncle Sam's ammo.
