.308 H015 .firing high at 50 yards when zero at 25

[cityhunter]

Hi
I bought my first Henry H015 in .308 single shot.
I zero at 25 yards with scope. Bulls eye.
At 50 yards it is giving 6 inches higher and at 100 yards nowhere on the target.
Any recommendations are appreciated.
Thanks

How high above the centerline of the bore is the scope?

any idea as to the muzzle velocity and specifics on the bullet

Id go back and rezero it at 50 and see what happens. Bullets are just starting the arc at 25 yards

Like Al said the bullet is still rising, it's a long range cabiler for Christ sakes.
I zero my 30-06 & Marlin 308 mx at 100 yds.

Agree with all above. Calibers like these cross line of sight at 25 yards and around 100+ yards without much arc height, I wonder if bullets are tumbling and catching air and flying off. I would try a 4x4 piece of cardboard too see if they will group or are tumbling or not.This is an interesting problem.

Back in the day we zeroed our M1's, M-14's and M-16's at 200yds. No scopes. I figure the younger generations must be really near sighted to have to use a scope at 25yds.

But besides the external ballistics, I suspect there's some significant parallax involved with his problem. The scope is probably indexed for 100yd no parallax, so 25 yds is going to be a problem.

Really need a lot more info to nail it down tho.

I like what PJM said. 4'x4' piece of cardboard with a 8" circle in the center. 50, then 100 yards. That may tell you[and us] something.

Thanks..let me try that.. Taking a big cardboard box and then try again.

But 6 Inches high from 25 yards to 50 yards is too high...
