Mmmm ....
Oh I don't know .... VFR 240Nm round trip gives payload of 1090 Kg (2400 Lbs) ..... IFR well that kinda depends on arrival Wx Alternates etc ...
You certainly won't do better in a 412 .... and with Perf 1 ??? AND Air Conditioning ....
I'm regularly going out 142 Nm (285 Nm) round trip and can offer customer 900 Kg ....
Customers .... LOVE it and so do I !
