I shoot the 325 grn Hornady LE out of my 45-70 Marlin Guide gun. I shoot for center at 25 yards, I get nowhere near an 8 inch drop between 25 yards and 100 yards, I get around 2 1/2 to 3 inches. Something is strange with a 10 inch elevation adjustment at 100 and little change at 25 yards as well as dropping 8 inches at 100 yards the first time around.
