Yep I've had a 7mm saum and 280ai in the past. The 280ai would actually suit the blaser action better. But the 7mm blaser would make the most of it and still be tolerable without brake or suppressor...
I’ve run the numbers on all 3 and there isn’t much in it.
The Saum is definitely the most efficient by the numbers.
Less powder and mid velocity the (280ai 2840fps) (Saum 2850fps) (BlaserM 2885fps +10gr powder)
That’s the QL results and I checked a number of powder options.
I ran a touch over standard length so seating them out will have an effect. The Blaser mag runs 5000 less pressure so 60??? The other two 65000. That’s just numbers though. @GWH has all the experience shooting the Saum.
180gr pills

I don’t actually have the saum real world data with the 180 so that 4 gns difference might grow not knowing where the saum would land with powder charge and 180s, it crossed my mind as soon as I wrote it that I’m comparing 168 real world saum for 180 real world blaser so apples for oranges I will certainly give it a go
Yip my blaser mag was 68gns of rl26 for 3060 with 180s so still very efficient my saum is 63.6 with 168s . Look at the 7LRM @PerazziSC3 brass should be easier to find and probably closest to the blaser and no longer doomed with average brass
This is from my 280ai and 180eldms. Currently in the process of developing a 168grn load which is showing promise.

Now I'm thinking 6.5prc... brass easy to get, still packs enough punch to 600m
