Excellent analysis - and it's always about bullet placement.

Faster isn't always better just remember tight groups if you want an accurate rifle it's not always about the speed
you might want to try Ramshot Hunter. I shoot a 30-6.8 western which has about the same usable case capacity and Hunter will get 60-75fps for the same pressure and lower case fill, it also has a better burn in short barrels than H4350.
if you can get an extra +/- 75fps and keep your accuracy it will extend your max range while keeping min velocity for proper bullet expansion making the experiment well worth it.

I had to switch to Magpro because of availability, and RL22 is a $70/lb. unicorn nowadays. It is the only powder I've used that I can't go to max charge weight. It peaks pretty quickly.

The two powders I use in my 300WSM's are RL26 and Superformance with the 168 gr TTSX. RL26 is about 100 fps faster but nearly impossible to find. Case fill was close to 100%. Superformance seems to be widely available and 67.5 gr under the 168 still has a bit of room to go both in terms of charge wt and case fill. This is my accurate load in 2 rifles and velocity is approx 3050 fps in 24"bbls.

Not a 300 am but I am running MagPro in a 270 WSM with 175gr Sierra TGK at 3050. It is a 7.5 twist 23" long.

RL16 is what I use in my 270 wsm. I've found that 58.2 grs will shoot any 130 gr bullet well, from .3 to .7 moa, ~3050-3187 fps. In my 2008 mod 70, which I love.
RL16 is slightly faster then H4350. You might get 100-150 fps more depending on the bullet weight.
It's a shame the wsm's have lost support from Winchester over the development royalties. Or whatever it is. The wsm's case sizes are in that light mag range, perfect for hunting imo.
Currently running 168 HHT in a 22" 1:10" and getting 3160 with N560, able to push it close to 3250 but not without significant pressure signs.
I also use N560 for medium to heavy (175 TA, 175 lrx, 205 bergers, 210 vld, 200 eldx) with good results with accuracy and velocity.
