200 yards the drop is like 3 to 4 inches.....out at 400 though , I think it drops off dramatically, like 25-27 inches.on the 130 grain, almost 40 inches on the 150...double check me on that ....there are dozens of good sites to confirm data on your exact cartridge....try

Bullets don't rise after leaving the barrel. A graft may give the false impression that they rise but the truth is they start losing speed after exiting the mussel and because of that start dropping. Because a scope is mounted above the bore of the rifle, a graft showing the line of sight and the bullet path cross twice. The distance that these two points are, depends on many factors including bullet weight, bullet coefficient, bullet speed and the distance you choose to zero your rifle in at. Here is a chart showing a .270 with a 130 gr. bullet. If you shoot 130 gr bullets this chart will get you in the ball park but you should shoot your gun with the actual ammo you plan to hunt with to know what it will do at any given distance.
You don't state above all the info needed to even give a good guess to answer your question but here goes. If your rifle is zeroed at 100 yds as in the chart, you would be 26" low at 400 yds.
