FMJ ammo is not target ammo as you know. Usually 3 moa is acceptable but I’ve seen some shoot better at times.
The trigger can be worked through just pay attention.
A 1/4” off at 50 yards will make a huge difference at 200. That’s why we should sight in at 200 and see where 50 hits. 4” high at 200 is not right but again, with FMJ ammo, it would be hard to call a zero, especially a 3 shot zero by centering the group at 200. Shooting a 10 shot group at 200 will give you a better idea of where zero is.
