It's a standard AR offset mount.

I only use the magnetospeed for muzzle velocities when doing load development. I never use it to do final sight in, and accuracy testing at yardage.

I put your info in shooter. 3.3 moa for 300 what it says. 2.75 scope height is standard for an AR. .444g1 2780 500yards 9moa. 1000 30.6 (this is at 6200 feet ).
Try tuning Streloc to by either adjusting the BC or speed. I was told by a very experienced shooter who makes hand pulled benchrest bullets for top national shooters that he prefers to play with bc until matching elevation with point of impact so that is what I do.

I tried that also. It didn't work either. I'm doing something wrong, I just have to figure out what. I had gotten frustrated with the apps yesterday and just gave up. I'll start from scratch today and see if I can get it figured out.
Applied Ballistics is the most reliably accurate phone app I've used. The Kestrel 5700X with AB on board is my preferred method these days... but I always have my profiles on AB app in my phone for a backup.
It's critical that you use a solver that accounts for aerodynamic jump.
A huge number of apps do not.

What's your altitude and baro pressure?
I have been extremely happy with Applied Ballistics Mobile App. It's worth the price and I have found it to be dead on from 100-1,000 yards. Another plus, is when Applied Ballistics tests a bullet for custom drag models or ballistic coefficients, you receive it for free. You are always up to date with Applied Ballistics. https://play.google.com/store/apps/details?id=com.appliedballisticsllc.appliedballistics&hl=en

I think the magnification level on a SFP scope doesn't matter if you are dialing. Only if you are holding

5.4 inches at 300 yards is 1.8 MOA so what's the problem?

You are doing something wrong. Plain and simple. I use Applied Ballistics and Ballistic AE.
First, learn the products better. Research and read/watch videos on all the details of configuring a App.
Make sure if you are doing MOA that everything is in feet and yards etc. All measurement systems need to be the same . MRAD do meters etc.
You'll get it

Threee likely issues to have that big of a difference:
1) The calculation is set up for a G7 and you are inputing the G1 value.
2) The scope is set up in your ballistic calculator as milRAD and you are assuming it's MOA.
3) Velocity is set up in your ballistic calculator as meters/sec instead of ft/sec.
Atmosphere won't make that big of difference at 300yds unless you lugged your rig up to the top of Everest. Nor will aerodynamic jump, Coriolis effect, or a litany of other factors.
I've used about a dozen different calculators over the years, at the ranges we are talking about they are at worst a click off. It's an input issue for sure. I'd recommend starting from scratch or your profile.
