I haven't owned many rifles that didn't immediately get scoped, so a recent issue with my open sight 45/70 has me wondering if I have stumbled onto something unusual.

Factory Ammo required the sight adjustment ramp be used on close to the middle notch, various handloads had me adjusting up or down a notch or so, but nothing major.
Then my must recent loading (a 300gr JHP @ 2100) went flying off to points unknown when shot at my 100 yard target...after moving up to 25 yards my shots began to just hit the top of the target. Well, even after moving the sight ramp to its maximum position to try to get the shots on target, I find myself still shooting almost 1 full foot high at 50 yards with this load.

So....is that odd, or do some loads just come with large shifts in POI?
