150 gr gamekings are awesome easy shooting bullets.
Imr 4350 is a great powder. Slightly temp sensitive so keep that in mind when working up loads now for deer season.
Nosler lists powder range of 55-59 grains of imr 4350 with 150 gr bullets.
I would load 3.320 coal
I would load 15 rounds starting at 55 and increase by 0.3 gr. Watch for pressure signs [ejector marks, stiff bolt].
Start on the low side and give your rifle plenty of time to cool down in between shots and work up.
If you can, shoot at 2-300 yards.
I presume you don't have a chrono... but if you do record each shot.
Your target will show you a pattern of getting tighter and further apart.
Find the spot where they hit together the closest and load a few and see what kind of group you can get. You will be less than 20 shots in and will have an idea what this gun is capable of in that combo.
I would guess the best you can expect is just under an moa.
Biggest improvement for me in factory 700s is a trigger upgrade. Big fan of trigger tech. Triggers are easy to replace.
Also bedding the action as someone pointed out.
Let us know how it goes.
