Thread: 7saum vs 280ai vs 7blaser vs?

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.

What pills and pressure

A 22" saum should go somewhere around 2950 with a 180gr with Re26. My 22" 284 can push 180s at 2830 easy as with re26. Saw 2900 in load development but she was well up there.

I have tried the 180s in my 22" Saum as yet. The 162s at 3050 kill so damn well even well out there around 750.

I have a 28 Nosler pushing 195s at 3100 too.

But the 7mm BM would be a nice option for sure if you could find some brass.

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

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

The blaser takes about 4gns more my mate ran his at 21” for 2910ish from memory with 180s

7lrm brass seems just as impossible. But yes that was certainly another option

Yip iv got my big pill slinger 180/195 on the way once the last of the parts arrive so trying the 180s in the saum is purely science I won’t be going away from the 160 weights

I found the recoil of BM not too different to RM, slightly sharper but very manageable even without brake or suppressor.

That’s great. I’ve loaded for a Saum but not the others. These are simply the numbers I got from QL as I said. They’re not real. It’s a guide at best.
I didn’t have any actual inputs other than the generated program ones.

This is from my 280ai and 180eldms. Currently in the process of developing a 168grn load which is showing promise.

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

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

Now your talking, your welcome to have a couple shots with my blaser one.

What length action is it?
