Seems you've got a good handle on 300wsm capabilities. My primary load in a factory 23" xbolt with h4831 and 200eldx @2.9" COAL is around 2840 FPS. With a longer throat, COAL, RL23 or RL26, and shorter bearing surface bullet like 200.20x berger I think it's reasonable to expect 2850 FPS.

I have a Tikka 300 WSM stock barrel (wanted to wait and see what speed I finished at before cutting down to 20”) so 24.3” I think.
I’m shooting Berger 200.20x at 2760 fps because it was too accurate there to push faster. I took it up over 2850 with no pressure signs in 60 degree temps, while I was still sun moa it shoots so much better at 2760 so I loaded up for season and long range drop verification. That was all H4350, I have H4831sc, IMR 7828 and RL26 to try after I have it cut down and TI pro break installed.
What are you getting for a COAL with the 200.20x? I'm wondering if I'll be able to run them at AICS magazine length or if I'll have to move that action to a stock and use longer mags.

Do you already own the Tikka? If not you need to get over that and look hard at a Zermatt Origin or the ARC Coup de Grace ($900) and if you go king action might as well go 300 PRC. You simply have more flexibility vs the WSM. Although I do think long throated WSMs are cool you won’t have to worry about meeting your goals handedly with the PRC.

Mine are 3.040” at 60 thousandths off the lands
Thanks for the info. I bought 500 of the 200.20x to use in a factory barrel. Looks like I'll be back to a stock instead of the chassis. Plans are a switch barrel 6.5 PRC and 300 WSM "truck gun" to drag around the state with me.
