With those parameters, NFBal shows 8.00 MOA @500yds.
However, 3300fps would get you to 6.0 MOA. (possible, but doesn't seem likely)
You may have several small errors adding up.
- MV faster in your barrel
- 100yd zero not exactly 100 yds or exactly zero
- 500yd target not exactly 500yds
- not exactly level ground
- scope clicks not exactly 1/4 MOA
- up/head wind
- recoil/bag setup different for 500yds vs 100yds allowing more muzzle jump
