Does that seem too low though for moving only twenty five yards. From dead center to almost two and a half inches low?
Yeah, it does seem like something is kaflooy.

Let's assume your 110 grain load of RS is pushing that pointy 300 grain bullet at around 1450 fps at the muzzle. With the scope crosshairs 1.5" above the bore and sighted in for dead on at 25 yards, the ballistics should look something like this.

Range.....Velocity.....Impact.....Drop.....ToF.....Energy
........0......1450............1.5............0.........00........1401
......25......1397..............0........0.64......0.06........1300
......50......1349............0.39.....2.39......0.11........1212
......75......1304...........-0.43.....5.34......0.17........1133
....100......1261...........-2.53.....9.58......0.22........1059

It should actually be hitting almost a half inch higher at 50 yards.

EDIT: And that's with a 25 yard zero. I forgot that you adjusted it to be one-inch high at 25 (shot #8). With that, it should have been over two inches high at 50.

At least, that's my figuring. We need help from some of the true ballistic experts out there.
