Feenix, that data might be wrong for the 270 Ackley...I don't even think a 7 STW could push a 175 grain to 3100. Good lookin charts though, great way to compare different loads/cartridges.
My 7STW load with 180 Berger VLD's is right at 2900 fps MV. I'd like to see the 7STW with Berger 168 VLD's...My load is at 2925 fps MV.

I would like to see the .280 AI calculated into that with the Berger 168 VLD's. As well as the 7RM with the 168 VLD's.

My 7RM 180 VLD load is right at 2830 fps MV.
My 7RM 168 VLD load is at 3,000.

I'm curious to see how these numbers stack up on the chart.

Seriously, no sarcasm, I would love to see how they do on the 1K chart in your ballistic program.

sorry for making it more complicated but I do like my Tikkas
I'm not sure about the WSM magazine length but if the Sako A-7 and the Tikka T3 magazine dimensions are the same, the max OAL for the 300 Win is right at 3.325" which is about .015" less than most manual recommended COL. The 178 A-max fits O.K. but you'll never get long bullets into that magazine unless the bottom metal is modified. I'm thinking 185 grain bullets might be all you can get into that magazine. CDI (CDiPrecision Gunworks) offers a solution to this issue if you want to shoot long bullets. I believe the twist on the Tikka 300 is 11:1 so you don't want to go with real long bullets anyway.

I personally would not trade a 300WM for a 300WSM. The standard OAL for the 300 is 3.34 but if you want to use like the Accubond 200gr or the Berger 210gr or heavier the mag box should be a minimum of 3.8 inches if you want to get it all the way to the lands. Of course where that is depends on the chamber but the big bullets are long.

Berger recommends a twist rate for the 210gr VLD of 1 in 11 or faster. So there you go...good luck.

With the right powder an stw is capable of 3100 fps with a 175. With the 50 bmg type offerings I was getting 3100 fps from my 24" bbl lh stw last fall with 171 barnes; and in the last rifle ( 26" sendero) I was pushing 175 hdy to 3100 fps with slow powders too. The h1000, rl22 class simply isn't slow enough to let the stw breathe enough fire without going over pressure.

Me too! Not sure of the difference in mag box but I have enough clearance up to 3.78" of OAL in my SAKO M995 in .300 Win Mag but only load to ~3.62" to play it safe.

Below are pix of 200gr NAB load ...

+1 on the right powder! Also, on barrel length and twist rate.

Why would you put up fictitious numbers and then highlight them, and that cartridge is not even in the discussion?
