Hey I'm loading for a 45 new Frontier 3rd Gen colt I see max loads in manuals for unique ranging from 7 to 9 grains for a 250 gr jacketed bullet for instance my Lyman book has a starting load of 7.8 and my Hornady book's max load is 7.4 grs i've loaded some rounds to 8.4 grains and now I'm wondering if I should pull them. What are your thoughts?

For a 250 grain JHP, my Lyman 48th edition reloading manual lists 7.8 grains of Unique for starting load @ 755 FPS and 8.7 grains @ 877 FPS as a maximum load, for standard loadings in Colt strength smokeless powder proofed revolvers.
This manual tends to be on the conservative side though, and most loads are cautious because of the possibility of being used in 100+ year old guns.
Your revolver is one with modern metallurgy though, manufactured in the late 1970s or later.
Your loads are perfectly safe in your gun, though unnecessary.
8.0 grains of Unique has been the standard load for both cast lead and jacketed 250 grain bullets since forever.
Plenty of power and easy on revolvers.

My favorite load was always my 230 grain Lyman #452374 RN cast bullet and 8 grains of Unique.
That mold was money well-spent because I used it in .45 ACP, .45 Colt, and .455 Eley (Colt, Mk. I).
Just a matter of sizing, or no sizing.
