I am not a caliber guru but I think bullets rise and then come back to dead zero, then begin the gravity drop. I shoot a Remington ADL 270 and love it. Have for 30 years....but I think it
comes back to zero at about 100 yards or so....I shoot 130 and 150 grain Cor lokt and I wanna say
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
